The Sloper is a unique name given to Australian bodied GM and Ford of the mid to late 30's. These bodies were first used on Oldsmobile, Chevrolet and Pontiac Chassis in 1935 and were designed by General Motors Holdens.
Richards Body Builders added the style to Dodge and Plymouth in 1937 and Ford Australia used the style in 1939/40. In addition a sloper style was also produced on Nash.
While Ford called their body aTudor, GMH named the style an All Enclosed Coupe.
