German WWII HJ Membership Diamond-This is a very nice example of an HJ membership pin. The enamel is very clear and scuff free. The colors are still bright. There is no crazing, cracks or breaks to this pin at all. The reverse has a function pin and the silver finish on this pin is intact, though darkly toned in spots (on the reverse). The reverse is nicely marked with RZM M1\93 for the rarely seen maker Gottlieb Friedrich Keck & Sohn. This is a very good example of a popular badge.
