Saloon, roadster, fixed-head coupé.

Essentially the traction as we'll meet it post-war, and development history as for 7C (grille, wheels, steering). Light 15 name used by Slough from '38, and pre'39 British cars usually have disc wheels. Slough's wooden facias have three dials in '37, two only thereafter. Post-war ones will have had less time to rust, but remember, there were no roadsters after 1940.
