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. This is an early pre-RZM (Reichszeugmeisterei) type badge, marked with 'Ges.Gesch.' The badge is of course complete with its functional pin/catch construction. Nice example in good used condition!
