Manufactured prior to the 1986 machine gun registration cutoff, both weapons in this lot are Group Industries transferable machine guns made in emulation of the Browning Model 1917 water cooled heavy machine gun. One of the most effective weapons deployed for World War I, the 1917 was sidelined by evolving doctrine calling for more mobile air cooled weapons, but continued to serve through World War II and beyond, while its descendants the 1919 and M2 would stand as signature American weapons through the bulk of the 20th century. These examples have been built using a combination of new made components and military surplus parts, primarily from the Swedish "Kulspruta M/1936", and installed in a dual gun framework for use in anti-aircraft operations or for heavy defensive emplacement use. The weapons are configured with mirrored feed, the left gun feeding from the left, the right gun feeding from the right, and both ejecting casings downward and belt to the center, but only the left weapon is fitted with a set of blade and tangent sights. Markings include Swedish "triple crown" crests on the water jackets, Group markings on the right sideplates, and two sets of sequential numbers; "3000222" and "3000223" on the Group sideplates, and "25107" and "25108" on the safety mechanisms in the supporting framework. Both weapons are fitted with a set of dual spade grips mounted on a buffer assembly, with a thumb trigger extension. Included with the lot is a black painted ground tripod.
