This is a scarce example of a WWII M2 ".30 Cal" lightweight air cooled machine gun, manufactured by the Buffalo Arms Corporation during late WWII/Korea. These were basically a scaled down version of the original Browning .50 Cal M2 Heavy machine gun only chambered in 30-06. These were typically used on various aircraft used during the early days of WWII in either a fixed wing version or on the back of various dive bombers like the Douglas Dauntless as a rear gun emplacement. They used riveted receiver design with a light weight barrel with the air cooled perforated barrel jacket. They had an unusually fast cyclic rate of fire, usually 1000-1300 rounds per minute. They used a cloth belt like the original M1917 and 1919 machine guns and also the later disintegrating metal links. They were replaced fairly early on with the heavier .50 Cal M2 MGs. The side of the receiver is roll marked with: "U.S. No. 115096 GVT INSPT". with a Cross-Cannon proof followed by "RLB" (NY District Ordnance inspectors initials), "BROWNING MACHINE GUN/CAL .30M2/BUFFALO ARMS CORP/BUFFALO NEW YORK U.S.A.". Beside that it is hand stamped PCC/Phoenix AZ", which we assume is an importer mark. This gun comes with an original WWII AMC (Appliance Manufacturing Company) 30 M2 tripod dated 1945 with a pintle, traverse and elevation mechanism (currently configured for a M60; can be reconfigured for the ANM2 with market-available parts), and approximately 100 disintegrating belt links.
