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.

Fine as professionally refinished, with 95% of the current blue, showing some rust spots and handling marks overall. Some old pitting has been covered by the blue, particularly on the underside of the receiver. The stock is fair, with cracks at the wrist, selector switch and near the receiver hinge, some of which have been internally stabilized with glue or filler. Mechanically fine.
