In 1937, Allard began producing modified Fords (in much the same way as the Chevrolet brothers had in the U.S.), selling them for £450 each. By the outbreak of war in 1939, twelve Allard Specials had been built. Sydney Allard's planned volume production was pre-empted by work on Ford-based trucks during the conflict. By the war's end, Allard had built up a substantial inventory of Ford parts.
