Original NSDAP Membership Badge – Marked RZM M1/127 – Alfred Stübbe Berlin

Original German NSDAP membership badge made of metal, a textbook example of political insignia issued between 1933 and 1945.
The reverse displays clear, embossed markings: the RZM logo within a circle and the maker code M1/127, identifying the firm Alfred Stübbe of Berlin.
The item features a horizontal safety pin mounted on a circular base, which remains fully functional.
The reverse surface exhibits a natural aged patina and visible signs of oxidation, confirming the badge's historical authenticity and period age.
The RZM (Reichszeugmeisterei) coding system was implemented to ensure standardized production and quality control for all National Socialist organizational insignia.
Manufacturer Alfred Stübbe was a recognized supplier in Berlin, and their products are well-regarded by collectors for their historical value and craftsmanship.
