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. The badge is maker marked with RZM (Reichszeugmeisterei) 'M1/105', indicating production by the company of 'Hermann Aurich' from Dresden. The badge is of course complete with its functional pin/catch construction. Nice example in good used condition!
