Originally developed near the end of World War I, Bergmann's MP18 was among the earliest submachine gun designs, and one of the first to fully settle the overall mission and pattern for the weapon; a compact, maneuverable weapon optimized for rough combat at "knife fighting" range. The MP18 was widely studied and dissected by the nations of the world, with many (licensed or contraband) imitators. Blade front and two leaf rear sights, with "THEODOR BERGMANN ABT. WAFFENBAU SUHL" on the left side of the receiver tube and the model marking and "1920" on top of the magazine well; while not documented, the "1920" mark is associated with weapons retained by Weimar Germany following World War I. Operation is open bolt, with full auto only trigger group and a manual hook safety. Fitted with a one piece semi-pistol grip stock with forearm grasping grooves and a flat steel buttplate. Included with the lot are two Bing Brothers second model "snail drum" magazines and one adaptor sleeve.

Fine as assembled and reactivated, with 70% of the arsenal blue finish, showing areas of brown patina, bright edge wear, mild spotting and light handling marks. The lower left side of the heat shield shows evidence of a repaired hole or weld, the interior of the receiver at the breech shows wear suggestive of a removed blockage, and the bolt assembly is a mixed-numbered replacement with a welded-on charging handle. The stock is very good, with a number of scuffs and scratches. Mechanically excellent.
