Only "Party" organizations come under the control of the RZM. Wehmacht organizations (Heer, Kriegsmarine & Luftwaffe) don't. If you seeany item from these organizations 99.9% it's a repro. There is one exception I know of and that's a Heer(Army) buckle marked RZM M4/44. This is the only original item I know of marked with an RZM code. There could be more but be cautious.
