The weapon was capable of firing up to 600 rounds a minute and, with an experienced crew, spare barrels and ample ammunition, was capable of maintaining that rate of fire for twelve hours. That endurance ensured that the guns were used on land, sea and in the air from 1912 to 1968. This limited edition kit features a finely-modeled gun with display frame.
