Hi, Greetings from Germany, I'm new in the forum, but known in Germany as a specialist for Reichsarbeitsdienst. The shown pins are only unofficially locally made - I name this "Reservistika". The Group 87 exist in Arbeitsgau VIII from 1933 - 1937. They are rare. But I know only this pin from 87 - I haben't seen other pins like this in my 20 year collecting German Labour Service. But there are other locally pins in different forms. All finds are chances. Michael Jonas
