The Devisme 1854 is a French six-shot percussion revolver in .35 caliber with a 6.5-inch octagonal barrel. The top strap bears a Devisme a Paris inscription in silver. The seller explains that each chamber sits on a post, and a left side lever locks the barrel assembly so that it seals the cylinder against the breech. The listing calls the system rare. The listing gives the .35 caliber and 6.5-inch barrel as the key configuration points.

This is an antique revolver for a display collection or for a student of unusual firing systems rather than a range gun. A New York buyer needs a pistol license before a dealer can transfer a revolver, and the gun is then added to that license.
