Original Engine number: AD3661
This 1930 4 1/ 2 litre Bentley is one of 667 production 4 1/ 2 litre cars manufactured by the Bentley Motors Company of Cricklewood, London between 1927 and 1931. Being preceded by both the 3 liter and the 6 1/ 2 litre the 4 1/ 2 litre was a development of the engine and chassis design of the 3 litre. The standard production model would produce 110 BHP and the ready turnability of the engine allowed for a considerable increase in power. The final development of the 4 1/ 2 litre was the supercharged model, inspired by the famous racing driver Sir Tim Birkin, of which there were 50 production examples and a further five cars built at Birkins Works, of which four were to form his Racing Team. In recent years, new supercharger units have been made to the exact original Amherst – Villiers design and a number of 4 1/ 2 litre cars have been modified to accept these units. The supercharged 4 1/ 2 litre Bentley has established itself as one of the most glamorous sporting motorcars ever built and in their racing, Le Mans trim have tremendous appeal as well as performance.
Chassis AD 3665 left the Bentley Motor Works on June 6th 1930 and was fitted with a Maythorn Weymann Saloon body.

After the War, the car was acquired by H. J. K. Townshend who was the most illustrious vintage Bentley restore of the 1960s and 1970s. Such was the quality of his work that any of the original Team Racing Bentleys that required work would be entrusted to his care, including the rebuilding of the two short chassis Birken Team Blowers. It is recorded in the original period “buff” UK registration log book that Townshend was responsible during his ownership of replacing the original bodywork with an open tourer body similar to or possibly being the one fitted today.
