One of the mainline American machine guns of World War II, the Browning 1919A4 was introduced towards the end of World War I as a lighter, air-cooled variant of the 1917 heavy machine gun, and would be put to work by infantry, vehicles, and aircraft. In the post-ar years it would find users on virtually every continent on the planet save Antarctica. Folding sights, with a blade front and a peep and notch rear sight with windage adjustments and elevation adjustment, a ventilated heat shield around the barrel, and the maker's markings on the right side of the receiver. The pintle and T&E mechanism are installed on the receiver, and a green painted, 1942 dated Lamson M2 tripod is included.
