Weird, Real Weird!
I've never seen a Luger stock with that type of attachment. I see no markings of any kind on the stock or attachment metal.
I would wonder if it is not from some country other than Germany?
Looks like it could be home made!....
It's a wasted trip baby. Nobody said nothing about locking horns with no Tigers.
I'm Spartacus, not really i'm Paul!...
Could it be for a Mauser C96 broom handle ?
It is similar to the stocks made in Japan in the 1960s to go with the toy Lugers they manufactured.
interesting view, any pictures?
