Usually the magazin-spacer is made of brass and not steel. However, there will always have been deviations depending on where spare parts were procured.

The magazine-spacer of my rifle is made of brass, the barrel shape is also typical for a rifle from Auguste Schüler, but the stock deviates a little from the typical german stocks of this time, and the Mauser 98 system is marked with the anchor sign of Krieghoff. According to Harald Wolf from Hatari Times, Krieghoff is also said to have built in Suhl rifle caliber 11,2x72. These weapons should look different than those of Schüler.
