Chassis 0447 GT is an early Ferrari 250 GT Boano Low Roof Coupé, bodied in lightweight alloy and notable as a transitional example between the Pinin Farina prototypes and the Boano series-production cars. Originally allocated a Pinin Farina body in late 1955, it was redirected to Carrozzeria Boano due to capacity constraints, then returned for cosmetic revisions before delivery in mid-1956. Its first owner was celebrated conductor Guido Cantelli, who perished in the Orly air disaster just months after taking delivery. The car subsequently passed through several American collections before a thorough engine rebuild was undertaken.
