1929 Bugatti Type 37

37385racingFrance
Engine
Unsupercharged inline engine, crankshaft with special hardening treatment

The 1929 Bugatti Type 37 (chassis 37385, engine 287) is one of the final batch of unsupercharged Type 37s produced at Molsheim, with its crankshaft receiving special factory hardening treatment. Delivered via Roubaix dealer André Mathon in June 1930, the car passed through a well-documented chain of northern French owners. Its most active competition career came under Gerard Herbaux, who raced it in at least five events between 1931 and 1933, consistently finishing and achieving class placings in events including the Grand Prix de Picardie, Circuit de l'Aisne, and Grand Prix des Frontières. The car was subsequently restored in the late 1990s or early 2000s.
