In the 1930s the company became less dependent on one car maker, and supplied coachwork to such as Alvis, Armstrong Siddeley, Bentley, Daimler, Lagonda, Rolls-Royce and Talbot. The company also updated its production methods and took to making small batches of similar bodies. With the outbreak of war in 1939, coachbuilding stopped and the company returned to aircraft work, manufacturing the wooden framework for the de Havilland Mosquito, one of the most successful aircraft of the Second World War. After the war, the company continued its association with de Havilland, and manufactured parts for the Vampire jet fighter.
