By October 1941, it became clear that Willys-Overland could not keep up with production demand, and Ford was contracted to build jeeps as well, using Willys blueprints, drawings, specifications, and patents, including the Willys engine. The Ford car was then designated "GPW", with the "W" referring to the "Willys" licensed design and engine. During World War II, Willys produced 363,000 Jeeps and Ford some 280,000. Some 50,000 were exported to the U.S.S.R. under the Lend-Lease program. For Bantam, jeep production stopped, Bantam received no further orders from the U.S. government and instead made two-wheel jeep trailers. This continued until the company was taken over in 1956.
