to do so. Even though it was trading at a loss in the depression years of the 1930s, the company was able to rely on reserves to keep going. In 1931, Albert Eadie, one of the founders of the company, died and his partner R.W. Smith died soon afterwards in 1933. Second World War (1939–1945) During World War II, The Enfield Cycle Company was called upon by the British authorities to develop and manufacture military motorcycles. The models produced for the military were the WD/C 350 cc sidevalve, WD/CO 350 cc OHV, WD/D 250 cc SV, WD/G 350 cc OHV and WD/L 570 cc SV. One of the most well-known Enfields was the 125cc 2-stroke Royal Enfield WD/RE, designed to be dropped by parachute with airborne troops. In order to establish a facility not vulnerable to the wartime bombing of the Midlands, an underground factory was set up, starting in 1942, in a disused Bath stone quarry at Westwood, near Bradford-on-Avon, Wiltshire. Many staff were transferred from Redditch and an estate of "prefabs" was built in Westwood to house them. As well as motorcycle manufacture, it built other equipment for the war effort such as mechanical "predictors" for anti-aircraft gunnery: the manufacture of such high precision equipment was helped by the constant temperature underground. After the war the factory continued, concentrating on engine manufacture and high precision machining. After production of Royal Enfield motorcycles ceased, the precision engineering activities continued until the final demise of the company. Postwar Model G and Model J and ex-military C and CO (1946–1954) Postwar, Royal Enfield resumed production of the single cylinder ohv 350cc model G and 500cc Model J, with rigid rear frame and telescopic front forks. These were ride-to-work basic models, in a world hungry for transport. A large number of factory reconditioned ex-military sv Model C and ohv Model CO singles were also offered for sale, as they were sold off as surplus by various military services. In 1948, a groundbreaking development in the form of rear suspension springing was developed, initially for competition model "trials" models (modern enduro type machines), but this was soon offered on the roadgoing Model Bullet 350cc, a single cylinder OHV. This was a very popular seller, offering a comfortable ride. A 500cc version appeared shortly after. A mid 1950s version of the Bullet manufacturing rights and jigs, dies and tools was sold to India for
