I think most of us like to depict our bikes in a wartime configuration and no doubt unit markings were often applied once the bikes were received by their respective units. I don't know how common it was for engines to be painted in REME workshops during the war. Certainly it was common practice post war. So in any case you would be depicting your bike as a REME workshop rebuild with a painted engine.

However though. Matchless did build bikes with various forms of painted engine and gearbox casings.

Did anyone notice that the BSA is in every way an early model, but has the speedometer drive on the left side.
