Light fighter in 1938 and remained in production throughout the war. The empty weight of the Battle of Britain-era Spitfire IIA was 2,142 kg (4,723 lb), increasing to 2,984 kg (6,578 lb) in a later variant. It was highly maneuverable and was generally a match for its German opponents. Most Spitfires had a Rolls Royce Merlin engine, but later variants used one of the most powerful engines of the war – the Rolls Royce Griffon. The Spitfire was produced and improved throughout the war but was complex to build and had limited range. In other respects it was considered an outstanding fighter.
Rolls-Royce Twenty Rolls-Royce Twenty The Rolls-Royce Twenty built between 1922 and 1929 was Rolls-Royce's "small car" for the 1920s and was produced alongside the 40/50 Silver Ghost and the successor to the 40/50, the Phantom. It was intended to appeal to owner drivers but many were sold to customers with chauffeurs. A new inline-6 cylinder overhead valve engine was designed for the car of 3127 cc with a bore of 76 mm and stroke of 114 mm. Unlike the Silver Ghost engine, the cylinders were cast in one block and the cylinder head was detachable. Both coil and magneto ignition were fitted.
