Montigny mitrailleuse
The Montigny mitrailleuse was an early type of crank-operated machine-gun developed by the Belgian gun works of Joseph Montigny between 1859 and 1870. It was an improved version of the "Mitrailleuse", () invented by Belgian Captain Fafschamps in 1851 which was a fixed 50-barrelled volley gun.

During the same period, French engineer Louis-Guillaume Perreaux, one of the pioneers of the motorcycle, had been working on a similar project since before 1860. Perreaux was granted a patent in 1864 for a multi-chamber gun. In 1878, Perreaux presented his invention at the World Exhibition of Paris.
