http://www.forgottenweapons.com Harmonica guns were a short-lived type of firearm that was developed in an effort to have reliable repeating weapons prior to the the modern centerfire cartridge. They were made in both muzzleloading and cartridge varieties, and one notable (and reknowned) American maker of such guns was Jonathan Browning, father of John Moses Browning. These two harmonica pistols was made by a man named Jarre in France (also a noted manufacturer), and both use pinfire cartridges. In addition, while early harmonica guns had to be manually indexed for each shot, these two automatically advance their slides when their triggers are pulled.
