Another thing you have to remember is that the M1 Carbine was a US service rifle and only Canadian troops serving under American command in the Second World War - such as the 13th Canadian Brigade in the Aleutians, the members of the First Special Service Force, or the Canadian Army Pacific Force - all trained with and carried US Army weapons. In Korea again, some Canadian battalions equipped themselves to a large degree with US weapons, the M1 carbine being especially popular among Canadians.
So how many Canadian soldiers were armed with the original issue M1 carbine during WWII ? and a paratrooper model to boot?? The odds would be few. Probably more Korean conflict bring backs.
