Early NSDAP Membership Badge 'Ges.Gesch.'

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 type badge which is nicely 'Ges.Gesch.' marked. The badge is complete with its original pin/catch construction which unfortunately is bent/flattened, see photos. Rare early example in good used condition!
