Manufactured with a combination of parts on an E.L. Goldman side plate. The Maxim design was the first successful self-powered automatic weapon, operating entirely on the discharge force of the fired rounds instead of being dependent on outside energy, making it the first "true" machine gun. While an early design, the inherent quality of the design made it a mainstay European heavy machine gun through and beyond World War I; its eventual retirement was more due to changing doctrines in favor of highly mobile air-cooled infantry machine guns than the introduction of a superior design. Blade front and folding ladder rear sights, with a Tula "arrow in star" mark and "1943" date added to the receiver cover, with (transliterated Cyrillic) "GV349" on multiple parts and a set of wood handled spade grips. The "Sokolov" pattern mount is finished in green paint, with integral traverse and elevation mechanisms, a set of steel-shod hardwood wheels, and a metal ballistic shield.
