1928 Bentley 4½-Litre Supercharged
- Engine
- 5.3L supercharged inline-four with Phoenix crankshaft

Bentley 4½-Litre chassis TX 3227, delivered in April 1928 as a standard 10-foot 10-inch chassis with a Harrison four-seat open tourer body and close-ratio D-type gearbox, has undergone significant transformation across its long life. Originally supplied to Mrs. Boyd of East Sussex, the car passed through several hands and, by 1961, had been amalgamated with parts from a 3-Litre chassis. Subsequent work included new side rails, Vanden Plas Le Mans-style coachwork, and eventual conversion to supercharged 5.3-litre specification around 2009. The car retains TX 3227-stamped front and rear axles as its primary identity markers.
