A concentration of info from a different thread:
"Members of the Naval, Military or Air Forces of Canada who have declared their willingness, or who have engaged, to serve in any of the said forces on active service beyond Canada and Overseas, during the present war, and who have been honourably ceased to serve on active service:
1.After not less than three months of continuous paid service.
2.By reason of physical disability.
For WW2 Army, at least there is a roll of their serial numbers that will give you the Regt'l number and name of the soldier it was issued to. I have a private researcher do my look-ups in Ottawa. There is sometimes an entry in the soldier's files too as to what number GS badge they got.
There seems to be x3 types involving language, consrtruction and fastener on the back. The Sterling ones were the early issue and may have been screwback only. The vertical pin vers. were to women who had no hole in their lapels.
WW2 GS WSBs I have are:
Sterling "General Service" Screwpost
Sterling "Service General" Screwpost
Sterling "General Service" Vertical pin
Enameled "General Service" Screwpost
Enameled "General Service" Butoniere back
Enameled "Service General" Butoniere back
Enameled "General Service" Vertical pin
WW2 GS WSBs I think I need are:
Sterling "General Service" Butoniere back
Sterling "Service General" Butoniere back
Sterling "Service General" Vertical pin
Enameled "Service General" Vertical pin
Enemeled "Service General" Screwpost
but am unsure if they even exist. I'm just extrapolating from the possible combinations of construction, language and fasteners. If anyone has an example of those I need, I would be pleased to at least have confirmation they exist.
