I do not believe this is WW II related.
The type of the skull does not seem something the Germans would have used...
Maybe from some SS DJ?
The ring tests positive for silver and I was thinkingof getting an xray for the exact composition of the metals. The only mark I can find is what looks like a S and A joined and I har not found a marker mark of this kind.
Looks like a bikers ring from the 70s!....
It's a wasted trip baby. Nobody said nothing about locking horns with no Tigers.
I'm Spartacus, not really i'm Paul!...
The head phones, as already mentioned, are nothing like any used during the war by the Germans.
A x ray will not tell what kind of metal the ring is made of and I believe it would be a waist of money. It is definitely a post war ring.
