1929 Bentley 4½-Litre Cadogan Tourer
- Engine
- 4.5L inline-four

Bentley 4½-Litre chassis DS3570, bodied by Cadogan Motors and despatched in July 1929, is an original-numbers example with a documented history spanning nearly a century. Following early use as a demonstrator by Gaffikin Wilkinson, it passed through several British owners including a period of active Bentley Drivers' Club use. A chassis-frame and front-axle replacement occurred after a 1930s accident, using genuine new-old-stock factory components. The bodywork was modernised in 1938 by H.M. Bentley, and a more recent restoration by James Pearce & Company returned the car to touring fitness.

Maintenance & restoration
- 1932Repair
Accident damage required replacement of the chassis frame and front axle; both were sourced as new-old-stock factory components, with the replacement frame stamped with the original chassis number DS3570, consistent with a factory Service Department fitment.
The replacement axle does not carry a number, distinguishing it from the original.
- 1938ModificationH.M. Bentley
Coachwork was updated in period fashion: front doors were cut down in a sporting style, and the wings, running boards, and valances were modernised. Telecontrol shock absorbers and an oversized fuel tank were also added.
Work carried out while the car was in the care of H.M. Bentley, the builder's brother.
- —RestorationJames Pearce & Company
Body restored after the 2007 sale; the 1938 H.M. Bentley coachwork modifications were preserved while further changes were made to support reliable extended-distance touring.
