Field Artillery Tractors played an important part in World War II, which was already highly mechanized. The various countries found variety of different solutions to the problem of towing heavy guns. Great Britain and the Commonwealth for example adopted 4-cheel drive tractors. Widely used in Europe and the Far East, CMP Artillery Tractors soldiered on through the immediate post-war years in both military and civilian guise. By virtue of their power and reliability many of these tractors survive today alongside more modern vehicles. Our model was produced by General Motors in Canada.
