1931 Rolls-Royce Phantom II Henley Roadster
- Colour
- Brewster Green

A Brewster-bodied Phantom II Henley Roadster on chassis 224AJS, one of only nine built on Phantom II underpinnings and among seven surviving examples. First delivered in 1934 to Texas cattleman Svante M. Swenson, the body was subsequently remounted onto chassis 224AJS by MIT chemistry professor Dr. Frederick G. Keyes, who retained the car for over three decades. Believed to retain original Brewster Green paint and black leather interior, the car has passed through a short succession of careful custodians and has never undergone a formal restoration.
