Did the proficency badge ever have a thin pin that is hinged? It is similar to the set up on war badges. I have one where the hinge mount divides the serial number. The number seems to be partially covered by the hinge. The number 49 is clear then there appears to be a patially obscured 3. Then the hinge mount seems to cover one number or perhaps two. On the other side of the hinge mount there is an 8. The badge is marked M1/101 and RZM. Also, the swastika is smaller than those on my other 3 badges. I am unable to post any pictures, Sorry. Thanks, Mike
