Hi all,
there is a lot of controversy regarding these badges including these made by Seilier (sp) & comp. of Geldern...M1/129 and this maker is one of the most copied by the Chinese.
They are apparently commemoration badges the originals were made be for 1933 (but with out dates) and reissued (sold) to aid party funds in approx 1935 so a person could show allegiance from the beginning of the party.
As you can see not a brilliantly made badge by any means, but these along with other artifacts of German Third Reich history can become a fascinating and complex area to research, wehrmacht-awards.com for further research.
