[fj43]

Hello, I need your opinion about this WWII dog tag. I'm not expert about this theme and I would to know more some informations about this dog tag. Is it military or reservist? And what is for 3.St.K. 66?
Thank you for your precious opinions, best regards,
Roby

Quite a common ekm, for a unit made up of mainly older men and fed into line units or used as installation or POW security.
