NSDAP Membership Badge (Parteiabzeichen). The badge is a late war painted zinc example, it has a nice age patina and has never been cleaned nor polished, only some minor paint loss. The badge is maker marked with RZM (Reichszeugmeisterei) 'M1/128', indicating production by the company of 'Eugen Schmidhäussler' from Pforzheim. The badge is of course complete with its functional pin/catch construction. Nice late war badge in good used condition!
