NSDAP Membership Badge 'RZM M1/14'

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) 'M1/14', indicating production by the company of 'Matthias Oechsler & Sohn' from Ansbach. The badge is complete with its original buttonhole attachement. Nice example in very good condition.
