Hey, so I have recently acquired a few BM m4 mini Ritter.. my question is this.. why are two of mine numbered and the third isn't??! I also noticed that the "cpm-m4" writing is different.. on the two that are numbered they just looked stamped, and the other one almost looks like it's got a circle around it.. please help?! Any explanation is appreciated..
(I know pictures would help, but Idk how to post them, but I can email them to anyone who is willing to help.)
Thanks in advance
