Wow, nice find if genuine.
I'm a collector of militaria and love 3rd Reich stuff, that doesn't ring a bell though, which is probably a good thing meaning it might not be all that common.
Then again, they had so many pins and badges.
Is that a date I see on the bottom ? Sure looks it, and is there anything visible on the back as far as inscription/manufactuer ?
The only think I could say about that with near certainty is it is a party design, and not military, and perhaps might even be a decoration of sorts.
