built around 1,600 Sopwith Camels, 250 Sopwith 1½ Strutters, and 200 Royal Aircraft Factory B.E.2s. The company, as Ruston & Proctor, was the largest British builder of aero-engines in the war, and built the largest bomb of the war. One of the directors, Frederick Howard Livens, had a son who was an army officer on the front line. Captain William Howard Livens was sent to Lincoln, where he developed the Livens Projector and the Livens Large Gallery Flame Projector. Neighbouring manufacturer Clayton & Shuttleworth also built planes. In 1919, Colonel J.S. Ruston was inspired to create a garden suburb in Lincoln – the Swanpool Garden Suburb. His vision was to provide affordable houses for his workers, with easy access to healthy outdoor recreation, such as a pleasure ground, cricket ground and swimming baths. Ruston purchased 25 acres of the Boultham Hall estate and established the Swanpool Co-operative Society. Architects Hennell and James of London created the designs for the houses, which were built between April 1919 and September 1920. The vision for the new suburb included a technical institute, church and schools. After running into financial difficulties the development was sold in 1925 to Swanpool Garden Suburb Ltd, a private company, but only 113 of the planned 2–3000 houses had been constructed and no more were built. The Ruston-Hornsby car After the Second World War the company attempted to diversify and one outcome was the Ruston-Hornsby car. Two versions were made, a 15.9 hp with a Dorman 2614 cc engine and a larger 20 hp model with 3308 cc engine of their own manufacture. The cars were, however, very heavy, being built on a 9-inch chassis, and extremely expensive – the cheapest was around £440 and the most expensive nearly £1,000, and within a few years other makers were selling similar vehicles that weighed only 3/4 ton and cost around £120–200 – and never reached the hoped-for production volumes. About 1,500 were made between 1919 and 1924, two of which are still retained by Siemens on the Lincoln site. One is fully restored in running/driving condition, while the second example is still awaiting attention. The R-H car was developed by the chief engineer, Edward Boughton, who joined the company in 1916 after helping to develop the tank. Later he would start the Automotive Products Group (APG) in Leamington Spa in 1920 which made Borg & Beck clutches, Lockheed hydraulic brakes,
