    This was a mid-war production of the Erma using leftover parts. The weapon is identical to the standard version except that it uses much the same stock as the earlier MP18 complete with finger grooves on the heavy fore end and the vertical pistol grip is eliminated. The 20 round magazine was also eliminated from further manufacture.
