W. Watson & Sons cane that doubles as a pneumatic air rifle. All metal construction painted to look like wood. Functions by unscrewing the lower barrel section from the top section and screwing the included air pump in its place to fill the tank in a similar fashion to using a modern day bicycle tire pump. Once filled, the lower barrel section can be screwed back together with the top section and loaded from the muzzle end with a ball and patch. To cock, the included square-tipped key is inserted into the hole two inches down from the joining section and turned. When the button, located 1 1/2 inches from the key hole, is pushed, the air from the tank inside the top section is released into the barrel, which pushes the ball out of the barrel at a high speed. The barrel has the ability to switch between calibers by utilizing a removable brass rifled .32 caliber screw-in sleeve, and has a brass smoothbore .43 caliber outer section. Screw-in brass tipped ferrule doubles as a wood ramming rod for loading. Provenance: The Larry Mattson Collection
