I am new to this site .I just got a knife with motto and RZM marked M7/13 with makers name the back of handel has been replaced with wooden grip and the front is proper but for the dimond which has the letters D and J when i pulled it apart the dimond was glued in place. I have since removed it but he back is not a normal pin back for uniform ? do you think it has been put on at a latter date to make it more expencive. I cant send photo at the moment dut will later.

Regards Paul
