Browning M1919A4 machinegun, chambered in 30-06 Springfield caliber, used in WW2, Korea and Vietnam wars. There were several similar versions (i.e. M37), but this one is the oldest one. Complements previous models: C74620 Traverse & Elevation Mechanism (ca.1942) US Army M2 Tripod for .30 Machineguns (ca. 1940) Many thanks to Nap Bollemeijer for his original work. This is a correction, completion and assembly of all parts, based on original blueprints from Rock Island Arsenal, Ordnance Dpt. of the US Army.
