This "air cane" measures 37 1/2 inches in overall length, is painted what appears to be a honey yellow and was likely originally painted to give it the appearance of bamboo, with small blade and notch sights and the ability to switch between calibers by utilizing a removable brass multi-groove rifled .30 caliber screw-in sleeve insert, and has a brass smoothbore .39 caliber outer section. The screw-in brass tipped ferrule doubles as a ramming rod for loading. The grip handle is horn. 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 trigger button, located near the key hole, is pushed, the air from the tank inside the top section is released into the barrel. Includes a walnut case, air pump, bullet mold, lead balls and tools. Provenance: The Dr. Robert D. Beeman Collection

Fine overall, retains 75% of the painted lacquer finish with scattered chips. The horn grip handle has some mild chips and few cracks. The case is also very good with general age related wear, some scratches, separated sections inside, an absent plaque on the lid and absent keyhole plate.
