Here is some research....
I give you: The Browning attached to the stock in all its glory. The stock on one side says Made in Canada and on the other it says "S.A. LTD 1945" And some text that was in blocked lettering that I can no longer read. Did my gun kill Nazis??
I dont know the story with the ammo belt, its always just been there.
Maybe it used to read Tactical?
