Hi
I have this SS dogtag. The only information that I have is that belong to "SS Baugruppe Ostland"

I have marked with pencil the letters, because they are to see.

Some more information? Thank you in advance!

On condition, 30-40 euros maybe, if it was in good condition maybe 50-60, but difficult to price such things, they are worth as much as you are wiling to pay?
