This Walther Sportmodell has a butt plate marked with an eagle/HZaGw marking over what I am guessing is eagle/Gw3. Despite the depot marking I cannot find anything else about the rifle which appears to have been repaired. I added the handguard. I realize it does not match in finish but it was the only handguard in my box of spares that fit. The bolt has no numbers on the bottom flat. Typically one will find the last three digits of the rifle's serial number in that spot. I do not know whether some Walther Sportmodells had factory unnumbered bolts or if the presence of the unnumbered bolts always means a replacement.
