NSDAP Membership Badge 'RZM 90 Ges.Gesch.'

NSDAP Membership Badge (Parteiabzeichen). The badge is a nice enameled example, it has a nice age patina and has never been cleaned nor polished, only some small scratches/dirt caused by years of storage and some minor enamel damage. This is an early transitional type badge, marked with 'RZM 90' and 'Ges.Gesch.' marked. The badge is of course complete with its functional pin/catch construction. Rare early example in good used condition!
