Where on the back of the buckle would the RZM be located?
Anzel, i have seen you post a few questions on HJ items now, are you a member of the HJ forum? its a good place to visit it wont steal you away from WRF, honest! it just if you have an interest there is much specialised info there thats not here aswell as much rare material
the second link above shows nice clear buckle markings!
