Speed of the Wind 1936 group

Eyston-Eldridge Speed of the Wind / Flying Spray

By William Pearce

As a teenager, Englishman George Edward Thomas Eyston was forbidden from racing bicycles by his parents. Unable to resist the thrill of motorsports, Eyston raced motorcycles under an assumed name to hide his activities from his parents. Eyston took a break from racing while he fought in World War I but returned to the sport shortly after the war, while he was in his mid-twenties. Eyston liked setting records, and in the late 1920s, he took on Ernest Arthur Douglas Eldridge as his Record Attempt Manager. Eldridge was a racer and record-setter in his own right, most famously setting a World Land Speed Record (LSR) on 12 July 1924 at Arpajon, France, driving the FIAT Mephistopheles at an average of 146.013 mph (234.985 km/h) over the flying km (.6 mi).

Many of Eyston’s records were set on the speed ring at the Autodrome de Linas-Montlhéry track south of Paris, France. He became such a prolific record-breaker that the French dubbed him “le Recordman.” Eldridge and Eyston believed that setting speed records was a better business than racing. In racing, the winner would only be on top until the next race, which would be in hours or days or a week. But with speed records, the publicity and sponsorship opportunities would continue until the record was broken, which could be months or years. In addition, a bad race could garner negative publicity, but a failed record attempt mostly went unnoticed. In 1934, Eyston and Eldridge designed a car specifically to set endurance records between one and 48 hours. The concept of such a car may have been partly inspired by John Cobb and his Napier-Railton racer, which was completed in 1933. The Eyston and Eldridge endurance car was named Speed of the Wind, although some sources refer it as Spirit of the Wind.

Speed of the Wind was large and streamlined, but had a rather conventional appearance for a record-breaker. The car was powered by an unsupercharged Rolls-Royce Kestrel V-12 engine. The engine had a 5.0 in (127 mm) bore and a 5.5 in (140 mm) stroke. It displaced 1,296 cu in (21.2 L) and produced around 500 hp (373 kW). A normally aspirated engine was selected for increased reliability for the up to 48 hours of continuous operation needed for the endurance record runs. The particular Kestrel engine acquired for Speed of the Wind had been used by Rolls-Royce to power a test cell ventilation blower. Rolls-Royce designed and built a special shallow oil pan to provide enough ground clearance for the low-slung engine installed in Speed of the Wind.

The engine was installed in the front of the car and powered the front wheels via a four-speed transmission. The front axle had independent suspension supported by a transverse leaf-spring. Watching Citroën cars going endlessly around the Montlhéry speed ring inspired Eyston to use the front-wheel drive configuration on Speed of the Wind; it struck him that the front-wheel drive layout might offer a slight advantage for endurance records on circular tracks. The front drive wheels pulled the car around the course without skidding, while cars with rear drive wheels had a tendency to skid as they were pushed around the course.

The “nostrils” on the front of the car seldom held lights and were often at least partially covered. The caps for the left and right fuel tanks are visible on the car’s sides, just in front of the tires. (Getty image)

At the very front of the car and cut low into the body was a rectangular slot that fed air to a radiator. Two large holes that resembled nostrils were cut into the bodywork above the slot. These holes housed lights and also supplied additional cooling air to the radiator. The holes were often either partially or completely covered during many record runs. Covering the holes was a way to improve the car’s aerodynamics when the cooling system was not fully taxed or when the lights were not needed. A three-core surface radiator for oil cooling was positioned between the engine and the cockpit.

The cockpit was located between the surface radiator and rear axle. The lack of a driveshaft to the rear axle of the front-wheel-drive car enabled the driver’s seat to be positioned very low. The driver was protected by a windscreen and had removable panels on both sides of the cockpit to improve streamlining and ease access to the car. A large fuel tank was located on each side of the car, between the engine and cockpit. The rear of the car tapered back and down, while a faring behind the headrest extended back to form a short tail. Speed of the Wind was built by the C.T Delaney works, in Carlton Vale, northwest of London.

The completed, but unpainted, car was tested at Brooklands in 1935. A special muffler system was added to quiet the car for the early-hour and somewhat secretive testing. Once everything seemed in order, Speed of the Wind was painted red, and the car and its team set off for the Bonneville Salt Flats in Utah, United States. On the same ship was Malcolm Campbell, also traveling to Bonneville to set speed records with the last of the Blue Bird LSR cars. Eyston and Ernest arrived at Bonneville in time to see Campbell set his last LSR on 3 September 1935. Campbell covered 1 km (.6 mi) at 301.473 mph (485.174 km/h) and a mile (1.6 km) at 301.129 mph (484.620 km/h).

In addition to the straight course setup for LSR attempts, Bonneville had circular courses 10 to 13 miles (16 to 21 km) in length (depending on the year and conditions) for endurance records. Earlier in 1935, American Ab Jenkins and Briton John Cobb had battled each other for various endurance records in their respective Duesenberg Special and Napier-Railton racers. When Eyston and Speed of the Wind arrived at Bonneville, Jenkins held most of the endurance records, including 24 hours at an average of 135.580 mph (218.195 km/h), covering 3,354 miles (5,398 km). One exception was the 10-mile (16.1-km) record, which was set by New Zealander Norman ‘Wizard’ Smith in the Fred H. Stewart Enterprise at 164.084 mph (264.077 km/h) on 26 January 1932.

On 6 September 1935, Eyston in Speed of the Wind established new records, covering 10 miles (16.1 km) at 167.09 mph (268.91 km/h), 100 km (62 mi) at 161.13 mph (259.31 km/h), 100 miles (161 km) at 159.59 mph (256.84 km/h), and 159.30 miles (256.37 km) in one hour. Mechanical difficulties with the front drive axle prevented the completion of additional endurance records.

Speed of the Wind was repaired, and another attempt was made on 16-17 September 1935. While slightly slower on the shorter records, Eyston and his co-drivers, Albert W. Denly and Christopher S. Staniland, managed to keep the car going for 24 hours. A 12-hour record was set at 143.97 mph (231.70 km/h), covering 1,728 miles (2,780 km), and 5,000 km (3,107 mi) was covered at 140.43 mph (226.00 km/h). The average speed for the 24-hour record was 140.52 mph (226.15 km/h), and a distance of over 3,372 miles (5,427 km) was traveled.

Flying Spray April 1936

With the Ricardo Diesel engine installed, the car became Flying Spray. At Bonneville in April 1936, the car now had an enclosed cockpit. Not seen is the cockpit cover. Note the disc wheel covers used to make the wire wheels more aerodynamic.

Earlier in 1935, rules governing vehicles powered by compression ignition (diesel) engines were officially recognized. Eyston had set numerous diesel endurance records which weren’t recognized in America, and the American diesel LSR of 137.195 mph (220.794 km/h) set by Wild Bill Cummings in the Cummins Diesel Special #5 on 2 March 1935 was not internationally recognized. Eyston saw an opportunity to break all existing diesel LSRs and set new world records that would be recognized by all.

British engineer Harry Ricardo had built a diesel, sleeve-valve version of the Kestrel. Known as the RR/D (Rolls-Royce/Diesel) or Ricardo Diesel. The engine could be fitted to Speed of the Wind with only minor modifications. Compared to the Kestrel, the Ricardo Diesel’s bore was decreased by .25 in (6.35 mm) to 4.75 in (121 mm). This provided room for the single sleeve valve around each cylinder. The sleeve valves were driven from the rear of the engine by a gearset that ran along the outer side of each cylinder bank. A new cylinder head featured a vortex-type combustion chamber with a fuel injector positioned vertically atop the chamber. The Ricardo Diesel displaced 1,170 cu in (19.2 L) and produced 340 hp (254 kW) at 2,400 rpm.

With the diesel engine installed, the car was renamed Flying Spray. An enclosed canopy was added to the car. In February 1936, the car was run at Pendine Sands, but no records were set. It was then sent to Bonneville, where on 29 April 1936, Eyston and the Flying Spray established new diesel LSRs. A total of three complete (out and back) runs were made, and the middle set was the fastest. Eyston set the diesel flying km (.6 mi) record at 159.10 mph (256.05 km/h), and the flying mile (1.6 km) record at 158.87 mph (255.68 km/h). These records stood until 11 September 1950, when they were broken by Jimmy Jackson in the Cummins Diesel Special #61 Green Hornet.

The spark ignition Kestrel engine was reinstalled, and the car was once again called Speed of the Wind. Two scoops were added atop the cowling to bring in air for the engine, and the cockpit canopy was discarded. Eyston and co-driver Denly were back at Bonneville in July to improve upon their endurance records. On 6 July 1936, a one-hour record of 162.528 mph (261.564 km/h) was set, breaking the old record by three mph (5 km/h). However, mechanical trouble brought a halt to the run before other records were broken.

Note that the nostrils are nearly covered, new intake scoops have been added to the engine cowling, and the enclosed canopy has been discarded.

The car was repaired, and Eyston and Denly set off in Speed of the Wind to break more records on 12 July 1936. The action did not stop until two days later, on 14 July. A 5,000 km (3,107 mi) record was set at 150.221 mph (241.758 km/h); 3,578 miles (5,759 km) were covered in 24 hours at an average of 149.096 mph (239.947 km/h); a 10,000 km (6,214 mi) record was set at an average speed of 137.453 mph (221.210 km/h); and a 48-hour record was achieved at an average of 136.349 mph (219.432 km/h), which covered 6,545 miles (10,533 km).

Eyston and Speed of the Wind were back at Bonneville in October 1937, along with Thunderbolt—an LSR car built by Eyston and Eldridge. Thunderbolt was powered by twin-Rolls-Royce R engines, and Eyston would race it and Speed of the Wind, which had been modified with an enlarged tail and a vane attached to its front right corner. The vane acted as a rudder to help push the car into the constant turn needed for the circular endurance course.

The taller tail and nose mounted vane are clearly visible as Speed of the Wind passes the camera at Bonneville in late 1937.

Jenkins and the Mormon Meteor II had established a new set of endurance records. In late October, Eyston and Denly made an attempt in Speed of the Wind to take the endurance records back, but inclement weather brought a halt to the endeavor. Another attempt was made on 3 November, and a new 12-hour record was set at 163.68 mph (263.42 km/h). In that time, Eyston and Denly had covered 1,964 miles (3,161 km). Speed of the Wind also covered 2,000 miles (3,219 km) at an average speed of 163.75 mph (263.35 km/h). However, the run could not be continued to 24 hours because the Speed of the Wind team had run out of tires due to the earlier attempt.

Eyston would spend the next few years setting LSRs in Thunderbolt and no longer focused on endurance runs with Speed of the Wind. At the start of World War II, the car was stored at Eyston’s workshop in Willesden, northwest of London. Speed of the Wind / Flying Spray (and the workshop) were destroyed by a German bomb during the London Blitz in late 1940 and early 1941. The Ricardo Diesel that powered Flying Spray was preserved and is on display at the British National Motor Museum in Beaulieu, England.

Cobb Napier-Railton Endurance Racer

By William Pearce

After John Rhodes Cobb made a small fortune as a fur broker, he started auto racing. Early in Cobb’s racing career, he served as a riding mechanic for Ernest Eldridge and his Mephistopheles racer, and he occasionally drove John Godfrey Parry-Thomas’ Babs racer on the Brooklands raceway in Surrey, England. In the late 1920s, Cobb had established himself as a capable, gentleman racer at Brooklands. His cars were often serviced by Thomas at his shop, located at the Brooklands raceway. The company was formed by Thomas and Ken Thomson, and renamed Thomson & Taylor in 1927, with Ken Taylor joining the firm after the death of Thomas during a Land Speed Record attempt.

Napier-Railton-Cobb

John Cobb sits behind the wheel of the Napier-Railton at the Brooklands track. The exhaust system with mufflers was a requirement for Brooklands and did a good job of muting the engine. Note the vertical bars covering the radiator.

In late 1932, Cobb ordered a special car from Thomson & Taylor that would be able to set lap records at Brooklands as well as establish endurance records up to 24 hours, with sustained speeds in excess of 150 mph (241 km/h). Cobb had previously set the Outer Circuit lap record at Brooklands three times, and it was a record that was special to Cobb. Cobb and Thomson & Taylor gave the task of designing the car to Reid Antony Railton, head engineer. Railton knew he would need to come up with a design that was strong, durable, and reliable to stand up to the rough Brooklands track and the prolonged endurance runs. The car Railton designed would be known as the Napier-Railton.

In selecting an engine for the new racer, Railton wanted something that was powerful and reliable—a high-performance engine capable of running at high-power for 24 hours. Railton selected the normally aspirated Napier Lion XIA. The Lion was a 12-cylinder aircraft engine with three banks of four cylinders. The center bank extended vertically from the crankcase, with the left and right banks angled at 60 degrees from the center bank. Normally fitted with a propeller gear reduction, the Lion XIA for the Napier-Railton was modified by Napier with a special, elongated crankshaft and the removal of the gear reduction. As tested by Napier, the special Lion XIA produced 502 hp (374 kW) at 2,200 rpm, 564 hp (421 kW) at 2,350 rpm, and 590 hp (440 kW) at 2,700 rpm. The engine was fitted at the front of the car and mounted between the chassis’ two large frame rails, which were 10 in (254 mm) tall. Five cross members secured the car’s frame.

Napier-Railton-Chassis

The chassis of the Napier-Railton with its Napier Lion engine and three-speed transmission. The two levers by the transmission were for the gear shift and driveshaft brake. The oil tank can be seen extending below the driveshaft and under what would become the cockpit.

Behind the engine was a single-plate clutch and the three-speed transmission. Since the car was to operate almost entirely at high speed, the first and second gears were much weaker than the robust third gear. This enabled the transmission to be smaller and lighter. The transmission drove the rear axle’s very strong differential, which had a 1.66 drive ratio. The forged rear axle housing was made of three sections: a center section that carried the differential, and left and right sections that carried the full-floating axle shafts. An oil sump, finned for cooling, was attached to the bottom of the axle’s center section. The car’s front and rear axles were positioned above the underslung frame rails, which enabled the car to have a low center of gravity. The suspension for the front axle used half-elliptical leaf springs, and the suspension for the rear axle used two sets of cantilever leaf springs on both sides of the car. The Napier-Railton was fitted with drum brakes on the rear axle and no brakes on the front axle. A driveshaft brake was operated by a hand lever and acted as a parking brake.

The chassis was covered by an aluminum body made by Gurney Nutting Ltd. The radiator at the front of the car was encased by the body, with a large opening for cooling air. At various times, the radiator opening was covered with vertical bars, a single bar, or no bars at all. The engine cowling had large humps for the left and right cylinder banks, a louvered top, and was secured by leather straps. Exhaust gases from each of the three cylinder banks were collected into separate manifolds, with the manifold for the center bank located on the left side of the car. An exhaust system consisting of a muffler and tailpipe extending to the rear of the car could be attached to each manifold. This system was used when the car competed at the Brooklands track. An undershield covered the bottom of the chassis.

Napier-Railton-Brooklands-grille

At 6 ft 3 in and around 240 lb, Cobb was one of the few that could make the large Napier-Railton look almost normal-size by comparison. The leather straps that secured the engine cowling passed through the humps covering the left and right cylinder banks.

The cockpit was behind the engine and offset to the right, with the driver’s feet to the right of the transmission. The throttle pedal was in the center, with the brake pedal on the right and the clutch pedal on the left. A raised scuttle panel and windscreen protected the driver. At times, an enlarged scuttle and a shield to the cockpit’s right rear were added to protect the driver from a burst tire. In addition, a covered mirror was occasionally fitted to the scuttle left of the cockpit. An 18 US gallon (15 Imp gal / 68 L) oil tank was positioned to the left of the cockpit. The tank extended under the driveshaft and below the driver’s seat, and its underside was finned for cooling. Behind the cockpit, the body of the car tapered to a short wedge. Housed behind the driver was a 78 US gallon (65 Imp gal / 295 L) fuel tank. The Napier-Railton had a 10 ft 10 in (3.30 m) wheelbase, a track of 5 ft (1.52 m), and was 15 ft 6 in (4.72 m) long. The car weighed approximately 5,000 lb (2,268 kg). Various tire sizes ranging from 19 x 7 in (483 x 178 mm) to 35 x 6 in (889 x 152 mm) were used throughout the car’s career, with smaller tires used for acceleration and larger tires fitted for top speed. The wheels were mounted to the car with knock-off hubs. For long record runs, the throttle could be held open via a cable, and lights could be added to the car. Push starting was employed to bring the Napier-Railton’s Lion engine to life.

The newly completed Napier-Railton made its debut for the press on 6 June 1933. Minor testing by Cobb and Railton occurred before the debut, and serious testing was carried out in July. The car’s public debut was at the Brooklands track on 7 August 1933. Cobb set a Brooklands standing start lap record on the first lap of the Napier-Railton’s first race, covering the 2.75-mile (4.43-km) course at an average of 120.59 mph (194.07 km/h). The Napier-Railton went on to win the short race.

Cobb then took the Napier-Railton to the 1.58-mile (2.55-km) speed ring at the Autodrome de Linas-Montlhéry track south of Paris, France for an attempt on the 24-hour record. Over 6 and 7 August 1933, American Ab Jenkins had established a new 24-hour record of 117.821 mph (189.615 km/h) driving a Pierce-Arrow V-12 at the Bonneville Salt Flats in Utah. This was the speed to beat. Cobb had previously arranged to use some equipment provided by George Eyston, a friend and fellow racer who was familiar with endurance runs at Montlhéry. The Napier-Railton’s exhaust mufflers were removed, and individual stacks were used. An angled shield was added to the scuttle left of the cockpit to block the exhaust flame glare from the center bank during night running. For the 24-hour attempt, Cobb’s co-drivers were Brian Lewis, Cyril Paul, and Tim Rose-Richards. Starting the record run on 2 October 1933, the car tore through its tires, and some difficulty was experienced with changing them. Push-starting the car after pit stops was also problematic. Rules stipulated that the car needed to travel forward under its own power. After shutting the car off during a pit stop, the crew needed to push it back some distance so that it could be pushed forward and started before it reached its original stopping point. Although several records were set with the Napier-Railton, including 200 miles (322 km) at 126.84 mph (204.13 km/h), 500 miles (805 km) at 123.27 mph (198.38 km/h), and six hours at 122.62 mph (197.34 km/h), the 24-hour attempt was abandoned after the radiator developed a leak and parts of the Montlhéry circuit began to break up under the car’s relentless pounding.

Back at Brooklands, Cobb and the repaired Napier-Railton set a new standing-start mile (1.6 km) record at an average of 102.52 mph (164.99 km/h) on 31 October 1933. On 4 November, the standing-start kilometer (.6 mi) record fell at 88.521 mph (142.461 km/h). Cobb was also timed covering 1 km (.6 mi) at 143.67 mph (231.21 km/h), the fastest speed recorded at Brooklands up to that point. On 2 April 1934, the Napier-Railton established a new Brooklands Outer Circuit lap record of 139.71 mph (224.84 km/h). Later that month, the Napier-Railton was back at Montlhéry for another 24-hour attempt. Cobb was supported by co-drivers Charles Brackenbury, Freddie Dixon, and Cyril Paul. Starting on 16 April, six hours passed at an average of 123.01 mph (197.97 km/h), 12 hours at 121.19 mph (195.04 km/h), and 2,000 miles (3,219 km) at 120.71 mph (194.26 km/h). On 17 April, after 19.5 hours had elapsed, Dixon lost control of the car, hit a guardrail and wound up in an infield ditch. Dixon was unharmed, but the Napier-Railton was damaged, and the record run was over. An AMR 33 light Army tank was required to pull the heavy car from the ditch. The Napier-Railton racer returned to the Thomson & Taylor works where it was repaired. At Brooklands on 6 August 1934, Cobb won the Championship Race and set a new Outer Circuit lap record at 140.93 mph (226.77 km/h).

Napier-Railton-Brooklands-jump

Cobb takes flight as the Napier-Railton transitions over the River Wey to the Railway Straight and Brooklands. The bridge over the river created a bump that caused faster cars to become airborne, an indication of how Brooklands was a rough track. The image illustrates both the enlarged scuttle and the rear shield added to protect the driver. Note the bar-less radiator housing.

In mid-August 1934, Jenkins increased the 24-hour record to 127.229 mph (204.756 km/h). Cobb still wanted to set his own 24-hour record, and Jenkins’ success on the 10-mile (16-km) circular track in the wide expanses of the Salt Flats convinced Cobb to make the trip to Bonneville in mid-1935. For the Bonneville record attempt, a 120 US gallon (100 Imp gal / 455 L) fuel tank with two filler necks replaced the 78 US gallon (65 Imp gal / 295 L) tank, and the side panels covering the engine were removed for additional cooling. Like at Montlhéry, individual exhaust stacks were used.

Cobb, his team, and the Napier-Railton arrived at Bonneville in early July 1935. Ever the sportsman, Jenkins had a lot of equipment already setup on the Salt Flats and left it there for Cobb to use. On 12 July 1935, Cobb established a new 1-hour record at 152.70 mph (245.75 km/h) and a 100-mile (161 km) record at 152.95 mph (246.15 km) while testing the car on the salt. Backed by co-drivers Charlie Dodson and Rose-Richards, Cobb and the Napier-Railton set 16 records over 15 and 16 July 1935. The average speed for 500 miles (805 km) was 147.66 mph (237.64 km/h); 1,000 miles (1,609 km) was 144.93 mph (233.24 km/h); 12 hours was 139.84 mph (255.05 km/h); 2,000 miles (3,219 km) was 137.86 mph (221.86 km/h); 3,000 miles (4,828 km) was 134.56 mph (216.55 km/h); and 24 hours was 134.85 mph (217.02 km/h). In that 24-hour period, the Napier-Railton covered 3,236 miles (5,208 km).

In its Bonneville configuration the Napier-Railton had a larger fuel tank, individual exhaust stacks, and its engine side covers removed. American and British flags were painted atop the radiator housing. The anti-glare shield appears in place on the left side of the car, but the windscreen is missing.

While Cobb achieved his goal, the record did not stand for long. At the end of August 1935, Jenkins increased the 24-hour record to 135.580 mph (218.195 km/h), covering 3,354 miles (5,398 km) in his new Duesenberg Special. In mid-September, the record was broken again at Bonneville, this time by George Eyston in Speed of the Wind, averaging 140.52 mph (226.15 km/h) and covering 3,372 miles (5,427 km). In three months, three groups of racers in three separate cars established three new 24-hour records, which varied by less than six mph.

After returning to England, Cobb and Rose-Richards won a 500-mile (805-km) race at Brooklands on 22 September 1935. The Napier-Railton averaged 121.28 mph (195.18 km/h), a speed that would not be bettered in a 500-mile (805-km) race until the 1949 running of the Indianapolis 500. On 7 October 1935, Cobb and the Napier-Railton set a final lap record at Brooklands of 143.44 mph (216.36 km/h). This speed was not exceeded before the track was partially torn up during World War II. During the attempt, Cobb covered 1 km (.6 mi) at 151.97 mph (244.57 km/h), the fastest speed recorded at Brooklands.

Napier-Railton-Bonneville-1936

Cobb starting an attempt for the 1-hour record in 1936. The electric starting motor can be seen just before the rear tire. The driver would pull the lever that pressed the roller against the tire. The electric motor would then be turned on, driving the entire car forward. With a little bit of speed, the clutch could be let out, forcing the ever-reliable Lion engine to turn over and fire.

In mid-July 1936, Eyston increased his 24-hour record with an average speed of 149.096 mph (239.947 km/h), covering 3,578 miles (5,759 km). Cobb had already planned to make another attempt on the 24-hour record. By early September 1936, Cobb was back in Bonneville with Brackenbury, Johnny Hindmarsh, and Rose-Richards as his co-drivers. The Napier-Railton had a new external electric starting motor that, when engaged, drove the right rear tire to effectively push-start the car. Also, an exhaust manifold (without mufflers) was fitted to the center bank to reduce the glare from the flames at night. On 10 September, using the 12-mile (19-km) course, Cobb set a new 1-hour record at 167.69 mph (269.87 km/h) and covered 100 miles (161 km) at 168.59 mph (271.32 km/h). On 12 and 13 September, the Napier-Railton established four new records, including averaging 156.85 mph (252.43 km/h) over 1,000 miles (1,609 km), 149.27 mph (240.23 km/h) over 2,000 miles (3,219 km), and 150.16 mph (241.66 km/h) over 24 hours, covering 3,604 miles (5,800 km). Cobb’s new 24-hour record was less than one mph faster than the previous record set by Eyston; once again, the record did not stand for long. In late September 1936, Jenkins took back many of the records and averaged 153.823 mph (247.554 km/h) for 24 hours, covering 3,692 miles (5,942 km).

The Napier-Railton raced only at Brooklands in 1937. On 29 March, it won a race averaging 136.03 mph (218.92 km/h), the fastest race ever run at Brooklands. On 18 September 1937, Cobb, co-driver Oliver Bertram, and the Napier-Railton won a 500 km (311 mi) race averaging 127.05 mph (204.47 km/h). This was the last time the car was run on the track. Cobb retired from circle-track racing to focus attention on his Land Speed Record (LSR) car, the twin-Lion powered Railton. Eyston and Jenkins continued their duel for endurance records, and Eyston tried for absolute LSR records with his Thunderbolt car. The Napier-Railton was stored through World War II and acted as an LSR car for the 1951 film Pandora and the Flying Dutchman. Installed for the film were a streamlined radiator housing, a headrest behind the cockpit, and an elongated tail.

The streamlined nose was made for the 1951 film Pandora and the Flying Dutchman and was removed in the mid-1950s.

After Cobb’s death while attempting a water speed record in September 1952, the Napier-Railton was used by Geoffrey Quilter of the GQ Parachute Company. The car remained mostly as it had appeared in the movie, but a smaller fuel tank was fitted, and a parachute testing structure was mounted above the rear axle. To improve stopping, discs replaced the drum brakes on the car’s rear axle. Quilter used the car for a number of years to test aircraft braking parachutes. Eventually, the original radiator housing replaced the movie nose.

The Napier-Railton was purchased by Patrick Lindsay in 1961. Lindsay competed in various Vintage Sports Car Club meets and other events, and was clocked at 165 mph (266 km/h) in the Napier-Railton. After Lindsay passed, the Napier-Railton was acquired by Bob Roberts in 1971. The car was restored to a configuration similar to how it appeared while being raced at Brooklands by Cobb. After Robert’s death, the car was purchased by Victor Gauntlett in 1987 and was subsequently acquired at auction by a German collector in July 1991. Following a protracted three-year negotiation, the Napier-Railton returned to England under the ownership of Lukas Hüni in early 1997. Under an agreement with the Brookland Society, Hüni held the car until funds could be raised to purchase the Napier-Railton for the Brooklands Museum. The car’s purchase was finalized in December 1997, and the Napier-Railton was officially handed over to the Brooklands Museum on 6 May 1998. The Napier-Railton, still equipped with its original engine, is on display at the Brookland Museum and is occasionally run for special events. Over its career, the Napier-Railton set seven records at Brooklands, 11 records at Montlhéry, and 29 records at Bonneville.

Blue Bird LSR Car Part 4: Campbell-Railton-Rolls-Royce (1933-1935)

By William Pearce

Starting in 1925, Malcolm Campbell had established himself as a notable record breaker, setting new absolute World Land Speed Records (LSRs) six times. The development of his Blue Bird cars, from the Sunbeam 350HP, to the Napier-Campbell, and to the Campbell-Napier-Railton, demonstrated a steady improvement in speed and design.

Campbell-Railton-R-R 1933 no body

With the Rolls-Royce R engine fitted, the chassis of the Campbell-Railton-Rolls-Royce Blue Bird is shown nearly completed in December 1932. It was fundamentally the same as when powered by the Napier Lion. Note the new coolant tank (just forward of the engine) shaped to fill up the empty space in the car’s body.

Shortly after setting an LSR over the flying mile (1.6 km) at 253.968 mph (408.722 km/h) on 24 February 1932, Campbell considered ways to exceed 300 mph (483 km/h). Campbell’s then-current car, the Campbell-Napier-Railton Blue Bird, was powered by a 1,450 hp (1,010 kW) Napier Lion VIID W-12 engine. After returning to England from the record runs in Daytona Beach, Florida, Campbell started negotiations with Rolls-Royce to acquire an R racing engine. The 1,900 hp (1,417 kW) R engine was originally developed for the 1929 Schneider Trophy Contest, and its output was increased to 2,350 hp (1,752 kW) for the 1931 contest. The engine powered the winner of both races—the Supermarine S.6 in 1929 and the S.6B in 1931. On 29 September 1931, a special 2,500 hp (1,864 kW) sprint version of the R engine was used to power a S6.B to a new absolute speed record of 407.5 mph (655.8 km/h).

Beyond the personal satisfaction these records offered Campbell, there was a fair amount of national prestige involved. In April 1932, Rolls-Royce agreed to loan engine R37 to Campbell. Campbell approached Reid Railton to redesign his car to accommodate the R engine. The Blue Bird car was soon taken to the Thomson & Taylor shop at Brooklands for modifications, which were overseen by Railton and Leo Villa. Because of the new engine, the car is often referred to as the Campbell-Railton-Rolls-Royce Blue Bird.

The Rolls-Royce R was a 60-degree V-12 that was supercharged by a double-sided impeller. The engine had a 6.0 in (152 mm) bore and a 6.6 in (168 mm) stroke. It displaced 2,239 cu in (36.7 L) and produced 2,350 hp (1,752 kW) at 3,200 rpm and 20 psi (1.38 bar) of boost. The 2,500 hp (1,864 kW) sprint version of the R made its power at the same rpm, but it used strengthened internal components and special fuels. The R37 engine sold to Campbell is often cited as a 2,500 hp (1,864 kW) sprint version which could operate at 3,400 rpm.

The R engine was longer, taller, and heavier than the Lion it was replacing. These differences necessitated changes to the Blue Bird’s chassis and body, but much of the car was unchanged. The engine was mounted to a subframe, which was then installed into the car’s frame. The three-speed gearbox was strengthened, and its ratios were updated to a 2.74 to 1 first gear, a 1.55 to 1 second gear, and a 1.00 to 1 third gear. The bevel pinion and a crown gear of the rear axle were driven at 1.2 to 1. The cockpit was still offset to the right, and the driveshaft was offset 7 in (178 mm) to the left. The left suspension had stiffer springs installed to help negate the engine’s torque.

The radiator was mounted to a new forward extension of the frame and enlarged to dissipate the extra heat generated by the more powerful engine. A new coolant tank, mounted directly forward of the engine, was made to conform to the shape of the engine and the car’s body. The car’s cooling system had a capacity of 36 US gal (30 Imp gal / 136 L). A forward-facing intake scoop positioned above the radiator increased engine boost by approximately 2 psi (.14 bar). The scoop ducted air under the coolant tank and to the engine’s four carburetors, located at the bottom of the supercharger housing. The 28 US gal (23 Imp gal / 105 L) fuel tank was still located behind the cockpit in the Blue Bird’s tail.

Modifications to the body were tested in the Vickers Ltd wind tunnel by Rex Pierson, and the chosen design was built by J Gurney Nutting & Co. The aluminum body sloped up from behind the radiator housing and formed two humps to cover the engine’s valve covers. The valve covers were actually exposed, forming the top of the engine cowling. The outer sides of the humps constituted the sides of the car’s body and had an exposed exhaust stack for each cylinder. The large cowling humps restricted visibility from the low cockpit, which was raised about 3 in (76 mm) to elevate the driver’s view.

The wheels, tires, and brakes were unchanged from the previous Blue Bird version. The front tires were 35 x 6 in (889 x 152 mm), and the rear tires were 37 x 6 in (940 x 152 mm). The tires were made by Dunlop, mounted to steel rims, and inflated to 125 psi (8.62 bar). Each tire and rim weighed approximately 224 lb (102 kg) and was secured to the car by 10 lug nuts. An aerodynamic disc made of aluminum covered each rim. Each wheel had a drum brake that was 18 in (457 mm) in diameter, 1.625 in (41 mm) wide, and machined with cooling fins around its exterior.

The Campbell-Railton-Rolls-Royce Blue Bird had a front track of 5 ft 3 in (1.60 m) and a rear track of 5 ft (1.52 m). The car’s wheelbase was increased 17.25 in (438 mm) to 13 ft 8 in (4.19 m), and its overall length was approximately 27 ft (8.23 m). It weighed around 9,000 lb (4,082 kg), which included approximately 1,450 lb (658 kg) of lead ballast by the rear axle intended to improve traction. With the more powerful R engine, wheelspin on the sandy beach was a serious concern.

The car was finished in December 1932 and had “Campbell Special” written on the tail fin. Campbell, his team, and the Blue Bird left for Daytona Beach in January 1933. When Campbell arrived on 2 February, the beach was found to be in such a poor state that only nine miles of course were available, and all testing was put on hold in the hope that conditions would improve. After delaying two weeks for a better course, a trial run was made on 14 February that ended with an overheated gearbox after the first pass. Campbell reported a very unsteady ride on the beach and lots of wheelspin; he also injured his left hand and forearm while shifting. Work was done on the gearbox to improve oil circulation, and another week passed with Campbell recovering from his arm injury.

On 22 February 1933, the weather and beach conditions were decent, and Campbell decided to make an attempt on the record. The R engine roared to life as the Blue Bird set off south down Daytona Beach. Speeds for the run were recorded as 273.464 mph (440.098 km/h) for the km (.6 mi), 273.556 mph (440.246 km/h) for the mile (1.6 km), and 263.540 mph (424.004 km/h) for 5 km (3.1 mi). The Blue Bird was serviced, and its tires, damaged by shells on the beach, were replaced. On the return north, the speeds were 271.473 (436.893 km/h) mph for the km (.6 mi), 270.676 mph (435.611 km/h) for the mile (1.6 km), and 251.340 mph (404.493 km/h) for 5 km (3.1 mi). New records were set at an average of 272.465 mph (438.490 km/h) for the km (.6 mi), 272.108 mph (437.915 km/h) for the mile (1.6 km), and 257.295 mph (414.076 km/h) for 5 km (3.1 mi). Campbell broke his own record by 18 mph (29 km/h).

Campbell was disappointed with the speed and felt it was the worst ride he had ever had in his life. The tires had been cut by sharp shells, and the wheelspin made the car very difficult to control. Campbell planned to make another attempt on 23 February 1933 but cancelled his plans as a result of his injured hand and the poor beach conditions. Before the team returned to England, plans were in motion to redesign the Blue Bird to achieve 300 mph (483 km/h). Ideally, a longer and better course could be found that had more consistent conditions. Also, Campbell officially stated that he planned to retire from LSRs once he surpassed the 300-mph (483-km/h) mark.

Campbell and crew returned to England on 8 March 1933, but work at the Thomson & Taylor shop to modify the Blue Bird did not begin until April 1934. There was no question that Campbell was going to stick with the Rolls-Royce R engine, and he purchased R37 for £5,800. The car’s gearbox was fine, but the rear axle was damaged. A new axle was designed that incorporated dual rear wheels. The hope was that having twice the contact surface driving the car forward would lessen the wheelspin and improve traction. The rear wheels used 110 psi (7.58 bar) of air pressure, while the front wheels used 125 psi (8.62 bar). The new axle used two pinions on the same axis, with each engaging a separate axle shaft. This would decrease the tooth load but resulted in staggered axles, with the left 1.5 in (38 mm) behind the right. The new gear ratio for the rear end was 1.19 to 1. The axle was resprung equally, and ballast weight was positioned on the left side of the car to counteract engine torque.

A vacuum air cylinder was positioned behind the cockpit to operate air brakes, located behind the rear wheels. Each of the two air brakes offered 2 sq ft (.19 m2) of surface area that would be presented nearly perpendicular to the airstream. The fuel tank was relocated to the left side of the car, outside of the frame rail and between the front and rear tires. Its capacity was 48 US gal (40 Imp gal / 182 L). The steering system was revised to incorporate a more conventional design with a single steering box and interconnected front wheels.

Campbell-Railton-R-R 1935 debut

The newly completed Blue Bird making its debut on 9 January 1935. The car’s streamlining was much improved. Note the relative positions of the cooling-air exit slot and the engine’s intake—this would later result in turbulent airflow into the intake. The right air brake can be seen behind the double-rear tires.

A new radiator was built that spanned the front of the car. Its new housing formed a wedge with an open slit at the front to draw in air. Using a lever in the cockpit, the slit could be closed for short periods of time to cut down wind resistance as the car traveled through the flying mile. The shape of the new radiator housing flowed into the new body, which was again developed through wind tunnel tests. The sides of the car now extended out to encompass the space between the front and rear wheels. A new tail fin extended back and up from the headrest behind the cockpit.

With the changes, and keeping all of the previous Blue Bird versions in mind, the press occasionally referred to the car as the Blue Bird V. The car had a track of 5 ft (1.52 m) and a wheelbase of 13 ft 8 in (4.19 m). Its overall width was 6 ft 11 in (2.11 m), and its overall length was 28 ft 3 in (8.61 m). The revised Blue Bird weighed around 10,450 lb (4,740 kg), including ballast.

During 1934, while the Blue Bird was being rebuilt, Ab (David Abbot) Jenkins was doing all he could to make the racing world aware of the Bonneville Salt Flats in Utah. Eventually, Railton met with Jenkins and visited the Salt Flats. Railton was impressed with that he saw and realized the LSR potential that the vast expanse offered. Campbell was also interested in the location. However, the Salt Flats were only usable in the summer and early fall, and the Blue Bird would not be finished until the winter. Because of the timing, the decision was made to take the car to Daytona Beach in January 1935. The Blue Bird’s chassis was finished in November 1934, and the body was completed in early January 1935.

Arriving in Daytona Beach on 31 January 1935, the team went to work to test the newly revised car. Test runs were made on 14 February, but the main issue affecting the team was bad weather and unfavorable conditions on the beach. Jenkins heard of the wait and traveled to Daytona Beach to speak with Campbell about the Bonneville Salt Flats. He also showed a film of speed runs on the flats. Jenkins spent three weeks in Daytona, and by the time he left, Campbell was planning to be on the Salt Flats in August 1935.

Conditions had improved enough for another test run on 2 March 1935. Issues were encountered with body panels warping next to the exhaust stacks and allowing fumes into the cockpit. Also, the car’s speed actually decreased when the radiator shutter was closed—it seemed like the engine would lose power with the radiator closed. The following day, after modifications had been made, the Blue Bird recorded a one-way speed of 270.473 mph (435.284 km/h). During the run, the beach was so rough that Campbell was lifted out of his seat and his goggles were pushed down, leaving his eyes with no protection against the speeding airstream. Campbell decided against making the return run.

It was not until 7 March that Campbell attempted another record run. The mile (.6 km) run south was completed at 272.727 mph (438.912 km/h). The return north was much rougher, but the Blue Bird covered it at 281.030 mph (452.274 km/h). The average was a new record of 276.816 mph (445.492 km/h) over the mile (1.6 km), 276.160 mph (444.436 km/h) over the km (.6 mi), 268.464 mph (432.051 km/h) over 5 km (3.1 mi), and 251.396 mph (404.583 km/h) over 5 miles (8 km). The speeds were well short of the 300-mph (483-km/h) goal Campbell had set. This was the last absolute LSR set on Daytona Beach.

Campbell-Railton-R-R 1935 Daytona

Part of the reason Campbell wanted to run on the Bonneville Salt Flats was to see if the sand at Daytona Beach was causing the discrepancy between the forecasted speed of over 300 mph (483 km/h) and the realized speed of 275 mph (443 km/h). While at speed, Campbell did not have time to look at the gauges and was unable to see if the engine boost pressure decreased when the radiator was closed. Back in England, A duplicate set of instruments were positioned in the right-side fairing. A light illuminated the instruments, and they would be recorded during runs with a Kodak movie camera to be reviewed later. Also, wind tunnel tests indicated that when the radiator slot was closed, the airstream was being deflected over the induction scoop, resulting in a decrease of engine power. The issue was solved by extending the scoop forward, past the opening for the radiator air exit. The Blue Bird was demonstrated at Brooklands on 21 April 1935 and then made ready for another LSR attempt.

The team arrived on the Bonneville Salt Flats in August 1935. Rolls-Royce had even loaned Campbell a spare engine, R39, to ensure the best possible outcome for the record attempt. Testing was done to make sure the rough salt surface would not damage the tires, and a perfectly straight and level 13-mile (21-km) course was completed on 1 September. A test run was completed on 2 September to make sure everything was in order and allow Campbell to become acclimated to the different surface. Some minor modifications were made to the Blue Bird, including increasing the clearance between the tires and wheel fairings to prevent the accumulation of salt.

On 3 September 1935, Campbell climbed into the Campbell-Railton-Rolls-Royce Blue Bird for an attempt on the LSR. Flying northeast across the open expanse of salt, he covered a mile in 11.83 seconds at 304.311 mph (489.741 km/h). When he closed the radiator opening, exhaust fumes filled the cockpit, and an oil mist covered the windscreen. At the end of the measured mile (1.6 km), the left front tire blew out at around 280 mph (450 km/h). Campbell had a rough time keeping the car under control; the tire caught fire, and Campbell stopped about half a mile (.8 km) short of where his crew was stationed. The crew loaded up their equipment and hurried to the car to prepare it for the return run. All six tires were changed, but the still-smoldering burst tire took much longer than the others. Barely within the hour time limit, Campbell was on the return trip southwest and covered the mile (1.6 km) in 12.08 seconds at 298.013 mph (479.605 km/h). He kept the radiator shutter open on this run and experienced a skid while braking.

Campbell exited the Blue Bird quite convinced that he had surpassed the 300-mph (483-km/h) mark. Moments later, the timekeeper informed Campbell that his speed averaged to 301.1 mph (484.6 km/h). An elated Campbell grinned broadly as the crew cheered. A few minutes later, while the team was tending to the Blue Bird, the timekeeper came back and said that an error had occurred. Campbell’s time was really 299.874 mph (482.600 km/h). Campbell was very disappointed but quickly recovered and said that he would make another attempt the next day. The team set to work preparing the car for another run. To solve the problem of exhaust fumes in the cockpit and gain some extra speed, an aluminum cockpit cover was quickly being made.

During dinner later that night, the timekeeper approached Campbell and took him aside. The timekeeper explained that a miscalculation had been made, and that he had actually gone 301.129 mph (484.620 km/h)—the initial calculation was correct. Campbell’s run in the Blue Bird was the first absolute LSR set on the Bonneville Salt Flats. Other records that Campbell set were 1 km (.6 mi) at 301.473 mph (485.174 km/h) and 5 km (3.1 mi) at 292.142 mph (470.157 km/h).

After setting the record at 301.129 mph (484.620 km/h), the Blue Bird was displayed in various locations. Seen here at the Scottish Motor Show in Glasgow in November 1935, the car is in the same condition as when it left the Bonneville Salt Flats. Note the extended engine intake and the front left body damage from the burst tire. The radiator slot is closed, and a Rolls-Royce R engine is in the background. (The Herald image)

Campbell was upset that the moment of his crowning achievement had effectively been taken away. True to his word, he retired from LSRs, and his run for the following day was cancelled. In a span of 11 years, Campbell had set nine LSRs, raising the record from 146.16 mph (235.22 km/h) to 301.129 mph (484.620 km/h). Within two years, Campbell would take on the even more dangerous challenge of setting Water Speed Records.

Campbell, his team, and the Blue Bird returned to England. The car was displayed in a number of exhibits and returned to the United States in 1937. It returned across the Atlantic in 1946. After Malcolm Campbell passed away on 31 December 1948, the car was purchased by his son Donald. Donald sold the Blue Bird in 1949 to acquire parts to complete the K4 hydroplane for an attempt on the water speed record. The Blue Bird returned to the United States and passed through a few owners and museums until it was acquired by the International Motorsports Hall of Fame and Museum in Alabama, which restored the car in 1996 to the Daytona 1935 standard (no extended intake). The Blue Bird returned to England in 2004 and 2013 when it was displayed at the British National Motor Museum in Beaulieu with the Sunbeam 350HP and Donald Campbell’s Bluebird CN7. The Blue Bird is currently displayed in the Motorsports Hall of Fame of America, located at Daytona International Speedway in Daytona Beach, Florida. A replica of the Campbell-Railton-Rolls-Royce Blue Bird is displayed at the Lakeland Motor Museum in Cumbria, England.

Campbell-Napier-Railton Blue Bird Malcolm 1931

Blue Bird LSR Car Part 3: Campbell-Napier-Railton (1931-1932)

By William Pearce

Malcolm Campbell got his start in setting Land Speed Records (LSRs) in 1924 with the Sunbeam 350HP. His next LSR car, the Napier-Campbell Blue Bird, had reached its peak in 1928. Campbell knew his car needed a redesign to beat Henry Segrave’s 231.362 mph (372.341 km/h) run in the Irving-Napier Golden Arrow. In late 1929, Campbell called in Reid Railton to see what more could be done to improve the Blue Bird’s speed. Railton was an automotive engineer who worked for Thomson & Taylor at Brooklands. The Thomson & Taylor shop started out as Thomas Inventions Development, founded by John Godfrey Parry-Thomas and Ken Thomson. After Parry-Thomas, a friend and former co-worker of Railton, was killed during an LSR attempt in 1927, Ken Taylor joined the company, and it was renamed Thomson & Taylor.

Campbell-Napier-Railton Blue Bird Malcolm 1931

Malcolm Campbell in the newly completed Campbell-Napier-Railton Blue Bird in January 1931. The car was powered by a 1,450 hp (1,010 kW) Napier Lion VIID W-12 engine.

Railton had the Napier-Arrol-Aster Blue Bird sent to the Thomson & Taylor shop. A few weeks later, Railton advised Campbell that if he could acquire a 1,500 hp (1,119 kW) engine, the car could be modified to reach 250 mph (400 km/h). Campbell would need the speed. Sunbeam was finishing construction of its Silver Bullet LSR car with the goal of reaching 250 mph (400 km/h), and the car was expected to make a record attempt later in 1930.

Campbell went to the British Air Ministry seeking the loan of the latest Napier Lion engine. However, the Air Ministry was reluctant to lend an engine and required a £5,000 deposit per engine. Campbell was not prepared for this expenditure, but his friend and powerboat racer Marion Barbara (Joe) Carstairs donated £10,000 to cover the cost. Campbell returned to the Air Ministry and was able to acquire two Napier Lion VIID engines. The supercharged W-12 engine produced 1,450 bhp (1,010 kW) at 3,600 rpm and was the same type that powered the Gloster IV floatplane, an entrant in the 1929 Schneider Trophy Contest.

Once the engines were delivered, the Blue Bird was built at the Thomson & Taylor shop. The frame, front axle, rear axle center section, steering system, and brakes were all retained. A new flywheel, clutch, gearbox, and rear axle shafts were installed. The Railton-designed three-speed gearbox had a 4.01 to 1 first gear, a 2.27 to 1 second gear, and a 1.24 to 1 third gear. The gearbox was offset 7 in (178 mm) to the left and allowed the driver’s seat to be offset to the right and lowered to about 10 in (254 mm) above the ground. The lower driver’s seat allowed the height of the entire car to be kept to a minimum. The enclosed drive shaft ran along the left side of the cockpit to the rear axle, which was also offset. The rear axle was encased in an aluminum housing and driven at 1.27 to 1 via a bevel pinion and a crown gear.

The chassis’ half-elliptic spring suspension was altered so that the left side of the car was more heavily sprung than the right. This resulted in the left side of the car sitting slightly higher than the right when the vehicle was at rest. However, under power, the torque of the engine would level the suspension so that the car was at an even ride height. Provisions for screw jacks were added to all four corners of the chassis. Having the simple jacks built into the car would decrease the time needed to change tires between record runs.

All tires were made by Dunlop, mounted to stamped-steel rims, and inflated to 120 psi (8.27 bar). An aerodynamic disc made of aluminum covered each rim. The front tires were 35 x 6 in (889 x 152 mm), and the rear tires were 37 x 6 in (940 x 152 mm). Each tire and rim weighed approximately 224 lb (102 kg) and was secured to the car by 10 lug nuts. The 18 in (457 mm) diameter and 1.625 in (41 mm) wide drum brakes with machined fins used on the previous Napier-Campbell Blue Bird were retained, but they were operated solely by a foot pedal and used a vacuum booster.

The body designed by Railton was tested and refined by Rex Pierson in the wind tunnel at Vickers-Armstrongs Ltd. The aluminum body was built by J Gurney Nutting & Co in 36 days. A new radiator was built to conform to the car’s new body. The radiator was mounted and cowled in its own housing at the front of the car. Air would pass through the radiator and be swept upward over the engine cowling. Having the radiator separate helped keep air out of the car’s body. The coolant tank was located in the main body of the car, just in front of the engine. The cooling system held 26 US gal (22 Imp gal / 100 L) of water. A 6 US gal (5 Imp gal / 23 L) oil tank was mounted next to the engine.

Campbell-Napier-Railton Blue Bird build rear 1931

The body panels of the Campbell-Napier-Railton were removable, except for the tail fin. A screw jack can be seen supporting the car. Note the “Napier-Campbell” lettering on the fin.

Just forward of the engine was a tachometer mounted to the cowling and covered with a fairing. This was installed to enable the driver to keep his eyes on the course and see the engine speed at the same time. It could also be used as a sight when the vehicle was at speed. The car’s wheel fairings were so large that they would contact the ground if a tire went flat. As a result, the bottom of the fairing was made of thin aluminum and designed to crumple without damaging the rest of the fairing in the event of a flat tire.

A small scoop “ventilator” was installed in front of the cockpit. It drew air into the cockpit, increasing its relative air pressure. This was done to prevent exhaust gases from accumulating in the cockpit and to prevent a back draft working to lift the driver out of the cockpit. A headrest positioned behind the offset cockpit tapered back into a large tail fin, which was also offset to the left of the car’s center. Behind the cockpit was a 28 US gal (23 Imp gal / 105 L) fuel tank. The filler for the gas tank was accessed by removing the headrest pad in the cockpit.

The car was finished in early January 1931 and had “Napier-Campbell” written on the tail. The car is often called the Campbell-Napier-Railton to eliminate confusion with other Blue Bird versions, and it is occasionally referred to as the Blue Bird IV. However, some publications continued to credit the car as Blue Bird III, and the American press mistakenly referred to it as the Blue Bird II. Campbell and his team continued to simply call the car “Blue Bird,” as they had done with the previous versions. The Campbell-Napier-Railton Blue Bird had a front track of 5 ft 4 in (1.63 m) and a rear track of 5 ft 2 in (1.57 m). The car had a wheelbase of 12 ft 2.75 in (3.73 m) and was over 25 ft (7.62 m) long. The top of the cowling was 45 in (1.14 m) from the ground, and the car had 5 in (127 mm) of ground clearance. It weighed around 7,950 lb (3,606 kg), which included approximately 1,450 lb (658 kg) of lead ballast by the rear axle intended to improve traction.

Campbell-Napier-Railton Blue Bird Daytona Beach 1931

Campbell sits in the Blue Bird on Daytona Beach in 1931. Note the cowl-mounted tachometer just in front of the engine. The aircraft (Stinson SM-2 Junior) in the background was hired by Campbell to fly Leo Villa from the start of the course to the turnaround after the first run. As the event played out, Villa watched the Blue Bird on the return run from the aircraft since Campbell did not stop between runs.

While the Campbell-Napier-Railton Blue Bird was being built, engine and gearbox issues caused the Sunbeam Silver Bullet to fall well short of its speed goal. But a new contender, an Australian named Wizard Smith, was working on the Fred H. Stewart Enterprise and intended to reach the 250 mph (400 km/h) mark. Smith planned to run his car on Ninety Mile Beach in New Zealand, which was of much interest to Campbell. However, after the trouble in Verneuk Pan, South Africa, Campbell was sticking with Daytona Beach in Florida until someone else found a better location. Campbell left for Daytona Beach in mid-January 1931 and arrived on the 29th, hoping to set a new LSR before anyone else could.

The car was quickly prepared, and Campbell’s first test run was on 31 January 1931. This was the first time the new Blue Bird got up to any serious speed, around 200 mph (322 km/h), as there was no reasonable way to test the car at high-power in England. During the run, in thick mist and haze, the spectating crowd had pushed onto the course and were nearly hit by Campbell making his return. On 2 February, Campbell hit 240 mph (386 km/h). The next day, he had reached around 260 mph (418 km/h) when the gearbox slipped out of third gear and the engine overrevved, potentially causing damage. A quick inspection found no issues with the engine, and the team decided against swapping it out for the spare Lion. Some images show the car with the tachometer on the cowling, while others show that it was removed and covered over. However, it is not clear if the tach was missing for the practice runs and added for the record attempt, or vice versa.

The car was ready for another run on 5 February 1931, which was another imperfect day with mist and fog and rough spots on the beach. With the Blue Bird pointed to the south, Campbell gained speed and shifted into second at 80 mph (129 km/h). He noted that the car did not accelerate as quickly as it had in the past, most likely a result of some engine damage from the over-rev. Once he hit 150 mph (241 km/h), Campbell shifted into third and kept his foot firmly on the accelerator, recording a speed of 246.575 mph (396.824 km/h) over the measured mile (1.6 km). Campbell immediately turned around and started the second pass without stopping. On his return trip north, the Blue Bird reached 244.897 mph (394.124 km/h). The average of the two runs over the flying mile (1.6 km) was 245.736 mph (395.474 km/h), a new LSR. Campbell bettered Segrave’s speed in the Golden Arrow by over 14 mph (22 km/h). Campbell also set a flying km (.6 mi) speed record of 246.086 mph (396.037 km/h).

Again in 1931, the cowl-mounted tachometer has been removed and covered. Note the opening between the radiator housing and the car’s body. The Daytona Beach pier is in the background, as is the Austin that Campbell drove to a Class H (under 750 cc / 45 cu in) record of 94.031 mph (151.328 km/h) on 6 February 1931.

Campbell and the rest of the team returned to England on 20 February 1931 and received many accolades. Campbell was knighted on 21 February by King George V, but Campbell knew that the Blue Bird could achieve faster speeds under better conditions. The Enterprise in New Zealand was still under construction and a possible contender for the absolute LSR. Although Campbell was the first person to exceed 240 mph (four miles per minute) on land, the 250 mph (400 km/h) mark was just a few mph away. After Daytona, the Blue Bird was sent on a brief trip to Buenos Aires, Argentina for a British Empire Exhibition. Once back in England, the Blue Bird was demonstrated at Brooklands on 24 May, and preparations were soon underway to return to Daytona Beach in 1932.

No significant changes were made to the Blue Bird for its LSR attempt in 1932. The radiator was slightly decreased in size and covered with a new cowling that had a smaller, extended opening. The cowl-mounted tachometer was removed, and the spare Lion engine was installed. However, some changes had occurred at Daytona Beach. The beach was a little over 23 miles (37 km) long, but a pier was positioned near its center, cutting the beach into two 10-mile (16-km) sections. Ten miles (16 km) had been enough room to set flying km (.6 mi) and mile (1.6 km) records, but it was a challenge to set 5-mile (8-km) records, and very difficult to set 10-km (6.2-km) records. As the absolute LSR was pushed higher, even the 10-mile (16 km) stretch of beach was becoming inadequate. To work toward a solution, some pilings were removed from the pier, creating a 50-ft (15-m) gap for LSR cars to speed through. However, even the most courageous of men, like Campbell, felt that trying to thread the 50-ft (15-m) needle at high-speeds was asking for trouble. The end result was that the course was extended beyond the pier, but not much. LSR cars would go under the pier at around 100 mph (160 km/h) while accelerating or under braking, depending on the direction of travel. No attempts were made to pass through the pier at top speed, and this left attempts on the 10-mile (16-km) record highly inadvisable for Daytona Beach.

Campbell demonstrates the Blue Bird at Brooklands on 24 May 1931. Note that the disc covering the rear wheel has been removed. The exhaust ports for the upper and left cylinder banks of the Napier Lion are visible.

Whenever possible, Campbell liked to set records on the same course and at the same time, with different sets of timing equipment recording the times for different distances. With the changes extending the course to 12 miles (19 km), Campbell and the Blue Bird would attempt LSRs up to the flying 10 km (6.2 mi). Campbell and team arrived at Daytona Beach on 10 February 1932—the Blue Bird was in perfect condition, but the beach was not. The pressure was on, as Wizard and the Enterprise were already in New Zealand and had set a 10-mile (16-km) record at 164.084 mph (264.077 km/h) on 26 January. The Enterprise was being prepared for an attempt on the absolute LSR as well as record attempts for longer distances.

After waiting for some time, the conditions on Daytona Beach had improved but were still far from perfect. On 20 February 1932, Campbell made a preliminary test run in the Blue Bird with rather rough results. On 24 February, while conditions were still improving, Campbell decided to make another test run south before a record attempt. Campbell liked what he saw and felt during the test run and decided to give the southbound leg all that he had. Aided by a 20-mph (32-km/h) tailwind, the Blue Bird covered the flying mile at 267.459 mph (430.434 km/h). The northbound return against the wind was at 241.773 mph (389.096 km/h), giving an average of 253.968 mph (408.722 km/h) over the flying mile (1.6 km). New records for the 1 km (.6 mi) and 5 km (3.1 mi) were set at 251.340 mph (404.493 km/h) and 241.569 mph (388.768 km/h) respectively. Speeds for the 5 mile (8 km) and 10 km (6.2 mi) were not recorded due to a malfunction with the timing equipment.

Campbell-Napier-Railton Blue Bird Daytona 1932

Campbell was a little disappointed with the speeds, and decided to try again. Rain prevented any record attempts on 25 February 1932, and although the 26th was clear, the wind had kicked up, and the beach was deteriorating. Campbell decided to make a run for fear that the conditions would continue to get worse. The speeds for the km (.6 mi) and mile (1.6 km) were slower, but he set new records for 5 km (3.1 km) at 247.941 mph (399.023 km/h), 5 mile (8 km) at 242.751 mph (390.670 km/h), and 10 km (6.2 mi) at 238.669 mph (384.101 km/h).

Just after breaking the 250 mph (400 km/h) mark, and even before returning to England, Campbell was considering what it would take to reach 300 mph (483 km/h). If the Blue Bird could reach 250 mph (400 km/h) with the 1,450 hp (1,081 kW) Napier Lion, then surely 300 mph (483 km/h) would be possible with a 2,500 hp (1,864 kW) Rolls-Royce R engine. It was not long before Campbell acquired an R engine and work on fitting it into the car began. This led to the Campbell-Railton-Rolls-Royce Blue Bird.

Napier-Campbell Blue Bird 1929

Blue Bird LSR Car Part 2: Napier-Campbell (1927-1929)

By William Pearce

When Malcolm Campbell set his first Land Speed Record (LSR) at 146.16 mph (235.22 km/h) on 25 September 1924, he knew the record would not stand for long. The Sunbeam 350HP Blue Bird that he was driving was an old design, and faster cars, like the Djelmo, were in the works. Campbell decided to start designing a car capable of 180 mph (290 km/h). However, there was still a little speed left in the 350HP, and Campbell upped his own record to 150.869 mph (242.800 km/h) on 21 July 1925. The car was then sold, and work concentrated on the new LSR car.

Campbell had used his connections with the British Air Ministry to acquire a 450 hp (356 kW) Napier Lion VA aircraft engine, which resulted in the car often being referred to as the Napier-Campbell Blue Bird, but it was also called the Blue Bird II. The Lion had a “broad arrow” configuration made up of three cylinder banks, each with four cylinders. One cylinder bank was in the vertical position, and it was flanked on the left and right by the other cylinder banks at a 60 degree included angle. The W-12 engine had a 5.5 in (140 mm) bore and a 5.125 in (130 mm) stroke. Total displacement was 1,461 cu in (23.9 L), and the Lion produced 450 hp (356 kW) at 2,000 rpm and 502 hp (374 kW) at 2,200 rpm.

With the engine on hand, Campbell turned to Amherst Villiers, a well-respected British engineer, to design the Napier-Campbell LSR car around the Lion engine. However, the relationship soured, and Villers left the project after the frame was designed. Italian engineer Joseph Maina, a friend of Campbell’s head mechanic Leo Villa, took up the project and designed the rest of the future record-breaker.

The Napier-Campbell LSR car was of a fairly conventional layout. The car’s C-channel frame rails were made by Vickers Ltd using a special steel with three-percent nickel. The frame’s four cross members were machined from solid forgings. The engine was installed near the front of the vehicle and behind a custom-made radiator. The 12 US gal (10 Imp gal / 45 L) coolant reservoir tank was positioned behind the engine and around the steering column. The steering column led to a cross-shaft with two steering boxes, each operating a drag link that extended along the side of the car to a front wheel.

The special three-speed epicyclic (planetary) gearbox was designed by Maina and Forster Brown. Part of Maina’s agreement with Campbell was that the Napier-Campbell LSR car would use his gearbox, as Maina and Brown were trying to market the design to the automotive industry. The forward speed gear ratios were a first gear of 3.0 to 1, a second gear of 1.5 to 1, and a third gear of 1 to 1. A reverse gear was also included. The shift lever extended from the right side of the gearbox. An enclosed drive shaft (torque tube) led from the gearbox to the rear axle. The rear axle was encased in an aluminum housing and driven at 1.27 to 1 via a bevel pinion and a crown gear. Behind the rear axle was a 12 US gal (10 Imp gal / 45 L) oil tank and a 24 US gal (20 Imp gal / 91 L) fuel tank.

The car was supported with half-elliptic spring suspension. The front tires were 33 x 5 in (838 x 127 mm), and the rear tires were 35 x 5 in (889 x 127 mm). The Dunlop tires ballooned to 5.85 in (149 mm) wide when filed with air. All four wheels used 18 in (457 mm) diameter drum brakes that were 1.625 in (41 mm) wide. The drums were machined with fins around their circumference to dissipate heat. The brakes could be operated by either a foot pedal or a hand lever. The Napier-Campbell had a front track of 5 ft 5.25 in (1.66 m) and a rear track of 4 ft 9 in (1.45 m). The car had a wheelbase of 12 ft 1.5 in (3.70 m) and was 15 ft (4.57 m) long. It weighed around 6,000 lb (2,722 kg).

The car’s Lion engine, Villers frame, and Maina gearbox were delivered to Robinhood Engineering Works, which was founded by Kenelm Lee Guinness. Here, the chassis was completed and made ready for the body. The car was then transported to Campbell’s Povey Cross estate where it could be completed under the watchful eye of Leo Villa.

The Napier-Campbell at Pendine Sands in early January 1927. The engine cowling has no louvers. A small windscreen sits ahead of the cockpit, and there are no wind deflectors by the cockpit sides. Note the water on the sand.

The aluminum body of the Napier-Campbell was made by workers from Jarvis & Sons and fitted as close to the chassis as possible. A large opening at its front provided cooling air to the radiator. Individual exhaust stacks for the left and right cylinder banks protruded from bulges in the engine’s cowling. Exhaust for the center cylinder bank was collected in a manifold that split into two pipes behind the engine, with one pipe exiting the left side of the cowling and the other pipe exiting the right side. The cockpit was positioned above the drive shaft, and the driver’s legs straddled the gearbox and its shifter. Two large tachometers dominated the dashboard, with one indicating the engine rpm and the other the driveshaft rpm. A small windscreen was positioned in front of the cockpit, and an aerodynamic headrest extended behind the cockpit. Behind the rear wheels, the car’s body tapered into an extended tail. When Campbell went to sit in the nearly completed car, it was found that the steering wheel needed to be removed for him to get in and out of the cockpit.

While the Napier-Campbell Blue Bird was being constructed, Henry Segrave, driving a modified Sunbeam racer, slightly increased the LSR to 152.33 mph (245.15 km/h) on 16 March 1926. The record was then decisively smashed by John Godfrey Parry-Thomas in the Liberty V-12-powered Babs on 27 April 1926 at a speed of 168.074 mph (270.489 km/h). Parry-Thomas upped the record to 170.624 mph (274.593 km/h) the following day. Parry-Thomas was looking to push his car further, and others were quickly closing in on Napier-Campbell’s target speed of 180 mph (290 km/h). To make matters worse, Sunbeam was constructing a special 1,000 hp car designed to propel Segrave to over 200 mph (322 km/h). If an LSR was in his future, Campbell and his Blue Bird would need to act fast.

The Napier-Campbell Blue Bird was completed on 30 December 1926 and taken to Pedine Sands for its first test on 2 January 1927. Running on the very wet beach, the gearbox was hard to shift, the brakes were very inadequate, and the cockpit design resulted in wet sand flying into Campbell’s face and covering his goggles. The car was returned to Povey Cross where work was done on the gearbox and brakes. A larger windscreen was installed, and wind deflectors were added just in front of the cockpit sides. A significant amount of air had been blowing out of the cockpit, and the updraft made Campbell uncomfortable. To redirect the airflow, vents were added to the car’s tail, and louvres were added to the previously smooth engine cowling. Some sources indicate a new racing version of the Napier Lion VA was installed. This engine had a higher compression ratio and produced 585 hp (436 kW) at 2,350 rpm. It was built for the Gloster II floatplane intended for the 1924 Schneider Trophy Contest, which was postponed.

Napier-Campbell Blue Bird 1927 Pendine Record

Campbell running at Pendine Sands in late January or early February 1927. The Napier-Campbell now has louvers on the cowling, a larger windscreen, wind deflectors by the cockpit, and vents on both sides of the tail. Note the single exhaust stack for the center bank protruding from the bulge in the cowling. Another stack is located on the other side of the car.

Later, in mid-January, Campbell returned to Pendine Sands but could only reach approximately 160 mph (257 km/h), not fast enough to set a record. The poor conditions caused part of the issue, but the car was still experiencing difficulties. Work continued on the Napier-Campbell while everyone waited for better weather. On 20 January, Campbell made a record attempt and achieved 166.38 mph (267.76 km/h) against the wind and 171.30 mph (275.68 km/h) with it. The average of 168.84 mph (271.72 km/h) was not sufficient for a new record. Campbell made two more attempts on the record, but the beach conditions prevented him from bettering his speed.

The Napier-Campbell was returned to Povey Cross for more work and in the hope that better conditions would soon prevail at the beach. Campbell and the car returned to Pendine Sands on 30 January 1927, but conditions were still far from ideal. On 3 February, Campbell had two furrows plowed along the beach to help drain water and make a strip of dry sand. The work was somewhat successful, and on 4 February, Campbell felt that the weather was tolerable and the beach sufficiently dry to attempt a record. On his first run, he covered the km (6 mi) at 179.157 mph (288.325 km/h). On the return, a bump lifted Campbell out of his seat, and his head hit the slipstream. The wind pushed Campbell’s goggles up his forehead, and he had to drive squinting and with one hand while he pulled them down. The mishap decreased Campbell’s speed to 169.291 mph (272.448 km/h). However, it was still enough to set new records, averaging 174.883 mph (281.447 km/h) in the flying km (.6 mi) and 174.224 mph (280.386 km/h) in the flying mile (1.6 km).

Although Parry-Thomas congratulated Campbell on the new record, he also wanted to win it back. On 3 March 1927, Parry-Thomas in Babs was trying to regain the record, when the car went out of control and crashed. Parry-Thomas was killed in the accident, becoming the first person to die while attempting a LSR. On 29 March 1927, Campbell’s record was obliterated when Segrave averaged 203.793 mph (327.973 km/h) over the flying mile (1.6 km) at Daytona Beach, Florida in the Sunbeam 1,000 hp Mystery Slug.

Campbell was not pleased that he had been beaten to 180 mph (290 km/h) and 200 mph (322 km/h). He knew the Blue Bird in its then-current form would not be able to exceed Segrave’s record, but with so much invested and now having become completely obsessed with setting LSRs, Campbell decided to rebuild the Napier-Campbell to surpass the 200 mph (322 km/h) mark.

The results of the rebuild left the basic chassis unchanged, but a new Lion VIIA engine was installed at the Napier works in Acton Vale. The engine produced 900 hp (671 kW) at 3,300 rpm and was similar to the one used in the Supermarine S5 floatplane that won the 1927 Schneider Trophy Contest. The Lion VIIA engine was considered “Secret,” and Campbell had negotiated conditions with the British Air Ministry for its use. Other changes included updating the rear axle to a 1.5 to 1 drive ratio. A completely new body was designed by Rex Pierson, chief designer at Vickers-Armstrongs Ltd, and based on results achieved in their wind tunnel. The front radiator was discarded, and a set of two surface radiators were installed on each side of the car, just behind the cockpit. The radiators were built by Fairey Aviation, and each panel contained 122 cooling elements and was 4 ft 7 in (1.40 m) long and 1 ft 7 in (.48 m) tall. The four panels had a total of approximately 2,400 ft (732 m) of tubing. Water entered the radiators by the cockpit and exited the lower rear side.

The car’s new body was built of 18-gauge aluminum by Barkers Ltd. The nose of the body was rounded and enclosed. It extended back to completely encompass the engine, without the bulges of the previous body. Exhaust from the center cylinder bank was now expelled via individual stacks protruding through the right side of the cowling. The scuttle and cockpit sides were built up to limit the amount of air and sand entering to cockpit. The cockpit sides slid down for driver entry and exit. Fairings were added behind the front wheels, and the rear suspension was completely enclosed in fairings. Two different size tail fins were made that could be added behind the cockpit to improve directional stability. The larger fin rose to a height about 8 in (200 mm) above the headrest, and the smaller fin extended back from the headrest fairing at a slight decline. As a result of the changes, the car’s length was extended by 3 ft (.91 m) to 18 ft (5.49 m), and its weight was reduced by a couple hundred pounds to around 5,820 lb (2,640 kg). The updated car was sometimes referred to as Blue Bird III.

The rebuilt Napier-Campbell racer was completed in January 1928, and Campbell and the car arrived in Daytona Beach, Florida on 12 February. The smaller tail fin was fitted for the record runs. During a test run on 16 February, the car struck some bumps at speed and became airborne. Campbell was lifted out of his seat, and when the car came back down, the underpan caught on the sand and was ripped off. The suspension was also damaged. The car was repaired, and on 19 February 1928, Campbell ran with the wind and covered a mile at 214.797 mph (345.682 km/h). Campbell noted the steering as very heavy, and he lost control immediately after the end of the run as the car slewed to the side. Fortunately, a quick recovery was made, but Campbell was quite shaken from the experience. Campbell decided not to change tires during the turn around for fear that he would not get back into the car. His return leg against the wind was a bit smoother and run at 199.667 mph (321.333 km/h). The average of the runs gave Campbell a new record at 206.956 mph (333.064 km/h), but he was so exhausted after setting the record that he needed help getting out of the car.

Campbell felt the updated Blue Bird could achieve a higher speed if the beach were in a better condition—a top speed of 220 mph (354 km/h) had been anticipated. Campbell also knew that his record would not stand long, as others, like Ray Keech and Frank Lockhart, were at Daytona to set records of their own. Segrave was also having another car built, the Irving-Napier Golden Arrow, scheduled to run in early 1929. On 22 April 1928 Keech broke Campbell’s record when he averaged 207.553 mph (334.024 km/h) in the White Triplex—a brute force, three-engine monster. On 25 April 1928, Lockhart lost his life in the Stutz Black Hawk when a tire blew at over 200 mph (322 km/h).

Campbell wanted to find a better course. The lack of traction in beach sand resulted in a lot of wheelspin, and a breeze always blew across beach courses, particularly at Daytona, that did nothing but cost speed. Among other places, there had been rumors of a large dry lake at Verneuk Pan, South Africa that would be ideal for LSRs. Campbell had searched various locales, even traveling to the Sahara Dessert, for an adequate speed record course, but he never found what he was looking for. An associate of Campbell’s had evaluated Verneuk Pan and believed it had potential.

During the search for a new course, Leo Villa had overseen work on another new body for the Naiper-Campbell racer. Again, wind tunnel test results were used to design the new body, which was built by Arrol-Aster and installed at their shop in Dumfries, Scotland. The surface radiators had proved not to be entirely effective and were removed. A new, conventional radiator was installed in the car’s nose. The front of the body was redesigned to incorporate a large opening for the radiator, which was later elongated and reduced in size. The front and rear wheel fairings were enlarged, as was the cockpit windscreen and cockpit opening. The sides of the cockpit were fixed, as was the tail fin, which was a redesign of the smaller fin used on the Daytona record runs. The revised car was called the Napier-Campbell-Arrol-Aster Blue Bird, but it is often just called the Napier-Arrol-Aster.

Once the Napier-Arrol-Aster was completed, the car, spare parts, and crew set off for South Africa. They soon discovered that Verneuk Pan was in the middle of nowhere, 400 miles (645 km) northeast of Cape Town, South Africa. The dry lake sat at 2,500 ft (760 m) above sea level, and there were no developed roads to the lakebed and no near-by workforce to build a course. But Campbell liked the huge, flat, open surface and the fact that the dominion of South Africa was part of the British Empire. Work on a 12-mile (19-km) course had started at the beginning of 1929, before Campbell arrived in South Africa (on 2 February). Once the course was prepared, small but sharp slivers of shale that would cut tires were found protruding from the surface. The top of the lake bed was scraped up, sifted to remove the sharp rocks, and then laid back down to dry into a hard surface under the scorching sun. As soon as the course was ready, massive rains came and flooded the area. It had not rained for five years, but suddenly there were 6 in (152 mm) of water covering the course.

On 11 March 1929, while a new course was being prepared at Verneuk Pan, Segrave in the Golden Arrow set a new LSR at 231.362 mph (372.341 km/h) on Daytona Beach. Campbell knew that he could not beat Segrave’s speed, but he was going to give a run all he had. The Napier-Arrol-Aster Blue Bird was brought out to the course on 18 April, and a record run was attempted on 21 April 1929. Campbell recorded 224.58 mph (361.43 km/h) on the outbound leg and 212.51 mph (342.00 km/h) on the return. The average speed of the runs was 218.54 mph (351.71 km/h), well short of the absolute LSR record, but enough for a British speed record (top speed achieved on British Empire soil).

The heavy Blue Bird broke through the surface as it ran, resulting in the destruction of eight tires. After some course improvements were made, on 25 April, Campbell set a new flying 5-km (3.1-mi) record at 216.04 mph (347.68 km/h) and a new flying 5-mi (8.0 km) record at 211.49 mph (340.36 km/h). That was all Verneuk Pan and the Napier-Campbell Blue Bird had to offer. The team returned to England, and after a six-week tour of South Africa, so did Leo Villa and the car.

Campbell wanted the LSR back, and before the car had returned from South Africa, he had been considering whether a new car should be built or if the Napier-Arrol-Aster Blue Bird could be rebuilt. The new speed goal was 240 mph (386 km/h) and beyond. At the end of 1929, Campbell enlisted Raid Railton to see what more could be done with the Napier-Arrol-Aster Blue Bird. Railton had some ideas, which led to the car being rebuilt as the Campbell-Napier-Railton Blue Bird.

A tribute to the 1927 Napier-Campbell was built by Lorne Jacobs using a 1921 Napier chassis (No. 14097). The Lion was acquired in 1930 by Lorne’s grandfather Gordon, long before Lorne was born. The two-seat car is registered for street use.

Note the then flag of South African on the car’s nose and the revised radiator opening, which has been damaged. Pictures from Verneuk Pan show the smaller opening undamaged. Most likely, the thin aluminum nose was damaged while the car was on tour in South Africa. The rod protruding from the nose was used as a sight while at speed on the large open lake bed.
