Developed in Paris and patented in the U.S. in 1862, Jarre's "breech-bar" system used a horizontal arrangement of pinfire chambers to supply repeating fire, which could be put to use on pistols, rifles, and even cannons. In operation, the bar is pre-loaded with 10 pinfire cartridges, all secured in place with a spring-retained bar, and is then advanced from chamber to chamber left to right by a push arm connected to the double action trigger. On this example, the chambers each have their own short barrel, but other examples use a single barrel. The right barrel is marked "A. JARRE/Bte S.G.D.G." The far left is marked "155." An ejector rod is screwed into the top of the grip section.

Good with mottled gray and brown patina, mild pitting, and general moderate overall wear. The grips are also good with moderate wear. The action is worn but generally functions with a weak trigger spring.
