This is a very nice original German NSDAP (NSDAP) Party Enameled Badge Pin, RZM Marked with M1/136, indicating it was manufactured by Matthias Salcher & Söhne of Wagstadt, part of the so-called "Sudetenland" that Germany Occupied as part of the 1938 Munich Agreement. After the war it became Bílovec in the Czech Republic. This is a somewhat rare maker, and only the second item we have had from them, the first being another NSDAP pin. Both are are somewhat unique in that they are made from magnetic steel, and not copper or zinc as with most makers.
The enamel is in very good shape, showing just a bit of discoloration and wear. The back has a very nice functional "safety pin" style attachment, which would work on any type of clothing.
Top pin!
