Indeed, Thanks everyone for all the help. I actually thought the store only sold fakes since one of the helmets labeled as an SS was entirely and utterly faked even as a 10yo kid I knew that. But anyway I think I'll be stopping by the store at some point during the summer and buying anything thats ww2. Thanks folks.
Since it has the Sig-runes added to the eagle , it would in fact have been for " SS & Polizei Fachführer & Fachunterführer Reichssicherheitshauptamt " and worth well more than the price mentioned .
Good thing it wasn't an original .. !
