   Modifications to the MP 18/I were suggested by Hugo Schmeisser in the 1920s. These modifications included the replacement of the angled feed collar used for the 32-round drum magazine with a straight design that could use a box magazine. For use with the straight collar was a Schmeisser-designed sheet-metal box magazine which held two columns of cartridges feeding to a central position. Both the magazine and the collar were included in a Schmeisser-held patent, which was signed over to the Haenel company in Suhl, Germany. Over the years between the World Wars, most of the existing MP 18/I weapons were converted to the box magazine.
