I noticed I didn't have a gun in my portfolio at all. Now I do.
This is a mid- to late 19th century harmonica pistol. Instead of rotating a drum to move another cartridge in line with the hammer, this just moves a completely new barrel in front of the hammer. It's a quirky design that was in no way successful, but led to a neat looking type of gun.
