I have this Thompson mag pouch for the 20 rnd mag which I'm not 100% certain is original WW2 production or what I call "historic repro", i.e. has gained a certain amount of patina of it's own. There appears to be no maker's or acceptance/ownership markings on it other than what's on the metal popper. I got it for a good price even if a reproduction. Thanks for any help and information.
