Magazine identification, now with pictures

[mrerick]

They are the group of four magazines in your first two photos, post #6.

Your "fxo" or "122" concealment marked magazines are all welded steel and milled into final form. The sharp edges indicate that they were milled. These were made by Haenel Schmeisser. After WW-II the plant was taken over by the East Germans, and brought into the Ernst Thalmann organization operations in Suhl. The "2/1001" concealment code was then used.
