Maybe an Austin A40 Sports?
Austin A40 Sports
The A40 Sports was a small aluminum-bodied convertible version of the Austin A40 Devon. Produced from 1950 through 1953, the A40 Sports featured a 4-seat 2-door body built by Jensen. It was very similar to the Devon saloon, though it used a twin-carburettor version of the 1.2 L engine for somewhat more power.
