Sidney Herbert Allard built a reputation in England as a prominent builder of competitive racers. The Allard Motor Company was founded in 1946, though Sidney had been building and modifying vehicles since the mid-1930's. The post war automobiles were mostly powered by Ford flathead V8s and often fitted with Sidney's own intake manifolds and cylinder heads. His J2X Sports Racers utilized the Cadillac and Chrysler OHV V8's continuing the tradition of American power in a British alloy body. Allard cars were seen at most every sports car race in 1950's.
This automobile was found in 1984 with a tree growing up through the middle of the chassis and has been fully restored. The automobile is believed to have been raced when new.
