Background
The Halford Special was a Grand Prix racing car of the 1920s built by engine designer Major Frank Halford on the chassis of an early Side Valve Aston Martin tourer. It was one of the most advanced British-built racing cars of the mid-1920s and had many racing successes. Halford himself was a freelance engine designer who did work for both the de Havilland Aircraft Company and Napier & Son.
