1931 Rolls-Royce Phantom II Henley Roadster

224AJSroadUnited States
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.

Maintenance & restoration

  1. 1938
    Modification

    The Henley body was transferred from its original chassis (217AMS) onto a lower-mileage replacement chassis (224AJS) at Dr. Keyes's instruction prior to his taking delivery.

    Chassis swap was carried out before the car was delivered to Dr. Keyes.

  2. Service
    Rolls-Royce service depot, Hythe Road, London

    The car was shipped to the Rolls-Royce service depot in London, where it received thorough mechanical attention, before being returned to Dr. Keyes in the United States.

    Carried out sometime in the early-to-mid 1950s, shortly after the 1952 Springfield RROC meet.

  3. Repair

    During Mark Gibbons's long tenure a new convertible top was fitted and certain brightwork was replated; no other significant work is recorded.

    Owner's intention was deliberate minimal intervention to preserve the car's original character.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
