Humpback auto shotgun, I think maybe the Rem copy of the Auto5 from the stock. A Jap milsurp,
hard to be sure, but I think the 7.7, but that bayonet may make it a 6.5, with dustcover. Not sure of
the next, maybe muzzle loader.
I have seen the .22 Semiauto with wood over the sides of the receiver, but do not
know the model. I the one on the right is a Benjamin air rifle.
Good start!
