Magazines of the 17th type are unmarked on both the left and right side of the housing, but they do contain the Spreewerk Waffenamt E/88 on the spine. The rectangular welding spots immediately indicate that the ENM factory was the manufacturer. These magazines were issued only with the early Spreewerk pistols.
