Scammell Lorries Limited was a British manufacturer of trucks, particularly specialist and military off-highway vehicles, between 1921 and 1988. From 1955 Scammell was part of Leyland Motors.
The Showtrac was a short-wheelbase 4x2 ballast tractor, one of the few vehicles ever designed specifically for fairground use. It could be supplied with a rear body (with half-height roller shutter access doors), winch, and dynamo with the ballast block underneath. Eighteen were built, to varying specifications (not all had the body fitted, for example), between December 1945 and September 1948. Seventeen have been preserved. There are many look-alike Scammell tractors, but genuine Showtracs had a special "Showtrac" badge on the radiator, and a full-width cab.
