The Walther magazines produced after the war have seven uniform circular welding spots. The floorplates have a rectangular notch, comparable to the wartime produced magazines. All of the magazines have ribbed followers that are an unfinished metal color.
This magazines is of an unknown variation. The top of the spine is stamped with a German military acceptance stamp and the production date was stamped on the bottom of the spine. The date of production indicates that the magazine should be of the first type. However the first variation was stamped with a so-called NATO stock number (NSN) on the spine. The NSN for a P.38 magazine was 1005-12-120-0892. However, this magazine does not have a NSN. Most military contract magazines have a phosphated finish. This magazine is blued. The lack of the NSN in combination wih the commercial finish makes it an odd variation.
