Opinion HJ buckle RZM M4/46

[saruman]

A great thank you to all for your help and for your very nice examples ! Glad to hear my buckle is genuine :-) I didn't know this maker !
Do you know why the pin/roller of it is in another color ? (I tested its not magnetic, maybe aluminium too ? )
Best regards

This maker Wilhelm Schröder also made HJ buckles in steel and nickel. For reference, here is my early nickel example. Other examples are in the main HJ Makers thread.
