The Hotchkiss M1909 Benet-Mercie Machine Gun was a French machine gun built in 1909, the gun was also known as the "Hotchkiss Mark 1" or the "M1909 Benet-Mercie". The French version used an 8mm Lebel. A variant to use the .303 round was produced in Britain as the "Hotchkiss Mark I" and manufactured by Enfield. The Americans also adopted the machine gun as the "Benet-Mercie Machine Rifle, Caliber .30 U. S. Model of 1909" which used the .30-06. The name Hotchkiss comes from the American who started the company in France, and the two main designers, Lawrence Benet and Henri Mercie.
