Inherited this from my grandmother about a year ago. Her father brought it back from France in 1918. I finally got around to cleaning it up because she never took care of it. It's a Mauser Oberndorf made Gew 98 mauser dated 1915. Anyway what is this odd attachment that you see here in the picture? It snaps onto the bottom of the stock and fits perfectly over the barrel. I wouldn't think this was some sort of stacking mechanism but maybe part of a grenade launcher sight?? Just a guess, does anyone here know?
