Forgotten Weapon: The Maxim Dual-Gun Tricycle

In 1895, Hiram Maxim responded to the U.S. adoption of the comparatively lightweight Colt M1895 machine gun (aka, the Potato Digger) by developing his own "Extra Light" version of the Maxim gun. By making his gun air-cooled instead of water-cooled and making many other parts lighter, he produced a machine gun in .303 British caliber that weighed just 27.5 lbs. (44.5 lbs. with its tripod). That was a major improvement over the standard Maxim, which often weighed more than 100 pounds with a mount.
