Aston Martin
The Bamford and Martin company was a small outfit, involved mainly with building racing and competition cars, and as such producing and selling a small number of cars. But things gradually changed when the Italian A.C. "Bert" Bertelli got involved with his new designs. His brother Enrico "Harry" Bertelli was the coachbuilder whose flair in body design helped commercial sales enormously, while the policy of continued competition use brought Aston Martin considerable publicity.
Post war David Brown (a specialist in tractors and gear making) purchased Aston Martin initially carrying on with the 2 litre 4 cylinder model, and shortly after using the 2 1/2 litre Bentley designed 6 cylinder engine designed for Lagonda (now also David Brown owned) for the new DB2, this engine being made into a 3 litre for the DB2/4 Mk2 and Mk3. By 1958 a new and larger 3.7 litre engine was built for the new DB4, which by 1963 had evolved into the DB5 with a 4 litre version of the same engine. A longer chassis and different styling led to the DB6 in 1965 which carried on in production to 1970. Concurrently with the DB6, another six cylinder model called the DBS , with much more "modern" bodywork, was introduced in 1967. From 1969 this DBS could be ordered with a 5.3 litre V8 engine, which unsurprisingly was called the DBS V8.
