The rectangular welding spots are characteristic for magazines produced by Erste Nordbohmische Metallwarenfabrik (ENM). JVD is the secret code assigned to ENM and this code was stamped on the spine. Also the ENM inspection stamp E/WaA706 was stamped on the spine. The position of these stamps may vary. No other markings were applied on this magazine variation. The rough magazine surface is typical for these late war ENM magazines. This magazine variation was only issued with Spreewerk and Mauser pistols that were produced in late 1944.
