I love hearing about these Singapore bikes. I mentioned the M20's from Singapore in 1957 when I was there in REME 40 Base Wkshops.
Well guess what ? I was back there with Royal Signals in 1966 (237 Signal Sqn) and 1971, (19th Signal Regt), did my army licence test on a WM20. What would be the chances it was the same bike ? I actually joined in 1956 (Parachute Regt), moved to REME for medical reason, then transferred to Signals 1965 until 1972. Luckiest squaddie in the army, I had 3 overseas postings, all in Singapore/Malaya.

There's rebuild and rebuild plates, here's one from 1945, a lot of 1940 G3WO's were already rebuild during the war, as they were in service since 1940, on mine I painted the rebuild number on the tank, it starts with C14, like all rebuilt bikes.
