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. The military contract magazines were stamped on the left side of the housing with the Walther banner, the pistol designation (either P.38 or P1), and the caliber.
The Bundeswehr (german postwar army) magazines were stamped with a Walther postwar inspection stamp on top of the spine. This inspection stamp resembles an eagle with drooped-wings over a number.
The Bundeswehr was part of the NATO organization and therefore was required to stamp all military equipment with a so-called NATO stock number. This number indicated an exact piece of equipment: for example, the NATO stock number for a P.38 magazine was 1005-12-120-0892 and was stamped on the spine. At the bottom of the spine is a code that indicated the production date (i.e., 6/58 for June of 1958).
