Your mag was not issued with the gun. The correct mag would be either a P.38 on the left side with e/135 for the very early guns, my "a" block has such a mag or P.38v on the left side with e/135 on the spine for later guns. I believe in February of 1943 the "v" was added to the mags.

jvd produced mags for all three manufactureres of P38's, most of their production was used later in the war. Mags that were issued with the pistol from the factory would have the WaA acceptance stamp on the mag along with any other markings that we see on jvd mags. A jvd mag without this would be a spare mag that was not issued with the gun for field use.

Here is a link to a late war rig I own that had two jvd e/359 accepted mags
