S/42 is the receiver marking on this Karabiner 98k, which the seller reads as a wartime maker code and date. The seller describes the rifle as mostly matching, with defaced proofs. It is used, in 8mm, with a 24 inch barrel and a matte black finish. The capacity is given as three rounds.

Defaced proofs are the usual sign of a rifle that came back from the war as a trophy or through a postwar program. The Waffenamt marks were scratched or struck to take away the German eagle. Many collectors accept them, since they are a part of the rifle's story, though a rifle with intact proofs commands more.

The 98k was the standard German infantry rifle in World War II. It uses the Mauser 98 action, a design that influenced rifles around the world. A mostly matching rifle is a good value.

Verify the markings when the rifle arrives, and check bore and headspace if you plan to shoot. It is sold as described. It ships to a licensed dealer you choose, and the background check is completed there.
