SA Diensthemd question.

[Crown]

Hi everybody! I came upon a listing for an SA shirt and I am leaning towards thinking its an older reproduction. The RZM tag looks nothing like other tags for similar items. (although I could not find much info on sa clothing tags) A couple of things i noted was how the number on the first set of lines is printed rather than stamped on, I don't think these tags were ever made in red and the font and placement is all off. The buttons are also something that i cannot find other examples. I just wanted to see if someone with more expert information on this could chime in.
