Original items. VERY few available. Just found in the back of the warehouse, we now have a very FEW original German made in 7.92X57mm MG 15 Air Cooled barrels that came as unissued spares with the weapons in an IMA purchase of 1999. Still in the original dried grease.
So very difficult to find and regrettably no longer importable. The MG 15 was a German 7.92 mm machine gun designed specifically as a hand manipulated defensive gun for combat aircraft during the early 1930s. By 1941 it was replaced by other types and found new uses with ground troops.
