Although modern reproductions are available there is, in my view, no acceptable substitute for a genuine pair of pre 1945 manufactured walnut grips for the PO8 Luger Pistol.
Confirmed by forum discussion this pair is in excellent undamaged condition with little if any wear apparent to the chequered grip pattern.
Nicely matched there are no obvious stampings.
