Lanchester 6x4 Armoured Car

Lanchester Armoured Car was a British armoured car produced in limited numbers in late 1920s and early 1930s. The vehicle remained in service with the Territorial Army and colonial units until early 1940s and saw action in the Battle of Malaya. It is often referred to as Lanchester 6x4 to distinguish it from an earlier four-wheeled design.
