The Tredegar M1916 Machine-Gun and it's accessories.
Developed in the late 1920s, the M1916 from the Tredegar Company was designed to serve as the standard weapon for the aircraft for the newly created Confederate Air Force, both as the main offensive armament for fighters as well as both a turret and a flexible mount for multi-seat aircraft such as bombers and recon aircraft. The weapon had a rate of fire of 1,200 rounds per minute and fed from a 65 round drum, and the weapon was fired from either a trigger mechanism (as shown above) or from a remote controlled mount. In addition to serving as an aircraft weapon, the M1916 was also used by ground forces with little modifications (such as the water jacket and a bi-pod.) The weapon would see service in several other militaries (as they often came mounted on Confederate built aircraft that were also exported), being used by South Africa, Argentina, the Dominican Republic, Mexico, Colombia, Russia, Venezuela, and Japan (which the Japanese Army had a licensed copy known as the Type 98.) Interestingly, the Tredegar Company submitted a modified version of the M1916 for the 1935 MG trials, which ended up losing out to Marlin's design which became the infamous "Ripper" machine-gun.
