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.

Leyland Motors Limited was an English vehicle manufacturer of lorries, buses and trolleybuses. The company diversified into car manufacturing with its acquisitions of Triumph and Rover in 1960 and 1967, respectively. It gave its name to the British Leyland Motor Corporation, formed when it merged with British Motor Holdings in 1968, to become British Leyland after being nationalised. British Leyland later changed its name to simply BL, then in 1986 to Rover Group.
