You are correct that these were mostly used by Home Guard units, and also by RCAF as they are sometimes marked with that. I would assume that the RCAF used them to guard bases and such in Canadaicon as there is no evidence these went over to Englandicon at all, and the ammunition issues would be problematic. I also read somewhere, but can't remember where, that they were also used by POW camp guards in Canada. Canadian used ones will all have a red band of paint over the fore stock to identify them quickly from P14's.
