"Ford C.M.P. vehicles used engines from both Canadian and United States factories although the Canadian engines were far more common. All Canadian-built Ford engines in C.M.P. trucks are prefixed with "G" and suffixed with ‘2F’. The prefix number denotes the engine model year, e.g. 1G is 1940, 2G is 1941, etc.: the ‘G’ denotes a Mercury 32.50 h.p. truck engine fitted with a four-speed gearbox. The suffix ‘2F’ means an export engine for Right hand drive vehicles. Starting number was # 1G-175 on 1 November 1939, and the last 1940 Model unit was # 1G-11500 on 1 October 1940; 1941 Models started at # 2G-205 on 1 October 1940 and ended at # 2G-48148 on 1 November 1941. The last known, so far, engine number is from a late 1945 F.60L, # 5G-11449F [a 1944 Model unit].
