Hotchkiss Mle 1914 machine gun

The Mitrailleuse Automatique Hotchkiss modèle 1914 (chambered for the 8mm Lebel cartridge) became the standard machine gun of the French Army during the latter half of World War I. It was manufactured by the French arms company Hotchkiss et Cie, which had been established in the 1860s by American industrialist Benjamin B. Hotchkiss. The gas-actuated Hotchkiss system was first formulated in 1893 by Odkolek von Ujezda and improved into its final form by Hotchkiss armament engineers, American Laurence Benét and his French assistant Henri Mercié.
