- 7.7L (468 cu. in.) overhead-valve inline-six, 40–50 bhp, three-speed manual

Chassis S359FM is a Springfield-built Rolls-Royce Phantom I carrying a Brewster Newmarket Convertible Sedan body, itself a close adaptation of a Murphy coachwork design, one of 67 such bodies fitted to Phantom I chassis. Delivered as a dealer demonstrator in New York and Boston before its first retail sale in December 1928, it passed through several notable American owners including a New York socialite, a Boston publisher with family ties to Amelia Earhart, and a California collector whose car appeared on the cover of a well-known restoration manual. The car has earned class recognition at prestigious concours events.
