During the Nazi era, Mauser Oberndorf originally had the factory code S/42. It was shortly thereafter changed to 42. In 1941, it changed to byf. In early 1945 it changed to SVW.
This is the same factory that had made Mausers since Wilhelm & Paul Mauser first introduced the Mauser Infantry Gewehr in 1871 and was a primary poroduced of Gewehr 98 long rifles during the first world war and K98k rifles during the second world war.
