7/5/19 - This is what we believe is a grenade launcher for a K98 rifle. The case, an barrel attachment piece, we believe are original. The tube doesn't have rifling which gives us pause on the authenticity, but it does look age and our understanding is that the earlier variations didn't have rifling and were used for smoke grenades / other utility type rounds. The waffen proof stamp and leather / stitching on the case appear original. The attachment piece also has a maker code and waffen proof stamp. The bottom of the case has some missing stitches but is still attached. Condition overall is great, and there's minimal wear on the launcher itself. Normal signs of aging.
