Overview

The Jarre Harmonica Gun is a mid-19th-century French repeating pinfire handgun built around a sliding horizontal steel block of chambers, typically ten, that advances across a fixed barrel as the gun is cocked and fired. Made in Paris by the Jarre firm in 7mm (and 7.65mm/9mm) pinfire, it offered high capacity for its era but was awkward to carry because the protruding block had to be removed for holstering. Patented in France and the United States between 1859 and 1862, it was made obsolete within a decade by self-contained centrefire cartridges.

Notes

Inventor recorded variously as A. Jarre or J. Jarre of Paris. Genitron lists .38 caliber (likely an error); auction and reference sources consistently give 7mm pinfire with 7.65mm and 9mm variants. Dimensions vary by example.

Background

The horizontal cartridge bar slides across the barrel like the mouthpiece of a harmonica being played, which is exactly how the gun got its name. Jonathan Browning, father of John Moses Browning, independently built American slide-bar harmonica guns, tying this oddball French design to one of the most famous names in firearms history.
