Here is my 1939 Railton Drop Head Coupe. Railton used Hudson built engines and chassis and assembled custom-built aluminum bodies (from several different body builders) in England. This is a one-off E.J. Newns body. Approximately 1600 Railtons were built from 1933 to 1939 (with about a dozen more assemblied in 1946 from left-over pre-war chassis).
Here the 3 position drop head (top) is down. This car is unique in that it is the only one I know of that the top completely disappears under a panel in the rear.
