NSDAP Membership Badge 'Steinhauer & Lück'

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 pre-RZM (Reichszeugmeisterei) type badge, maker marked by the company of 'Steinhauer & Lück' from Lüdenscheid and 'Ges.Gesch.' marked. The badge is of course complete with its functional pin/catch construction. Rare early example in good used condition!
