Ferrari 750 Monza chassis 0510 M was delivered new to Texas oil-equipment manufacturer Allen Guiberson in 1955 and immediately campaigned by Phil Hill and Carroll Shelby, most notably finishing a disputed second overall at the 12 Hours of Sebring before winning the Del Monte Trophy at Pebble Beach. Subsequently acquired by the Hall brothers, the car gave Jim Hall his first motorsport victory and remained in his custody for over six decades. Restored in the 1990s to its original white-and-blue livery, it is regarded as one of the finest surviving examples of the type.
