I have a chance to pick up a Broom handle and I am having a hard time to find another like it. This one has less of the sides machined away meaning the sides are more flat and it also has a selector switch on the left hand side of the gun, in the down position it points to the letter R up is the letter N... It also has a couple Chinese symbols on the mag well, But it has markings from Mauser also .. Any info is appreciated .. Thanks
