Manufactured by Haenel and imported by the Inter American Import Export Company of Sacramento, California, this is a fine example of the MP28.II SMG. A refinement of the World War One era MP18 SMG, the MP28.II was part of the last generation of "heavy metal" SMGs, prior to the transition to the MP38/MP40 models for the Germans. Blade front and tangent rear sight graduated to "10", with a ventilated receiver that doubles as a heat shield for the barrel and a magazine well marked "M.P.28.II/SYSTEM/SCHMEISSER/PATENT". The underside of the receiver bears the Inter American markings. A manual hook safety is integrated into the receiver, with a "D" and "E" marked pushbutton selector switch built into the trigger guard. Fitted with a smooth pistol grip stock with grasping grooves on the forearm and a ribbed steel buttplate. With two extra magazines.
