Introduced in 1963, the Walther MP ("Maschinenpistole", literally Machine Pistol) was a major competitor against the Heckler & Koch MP5 as a military and police weapon, with users among many West German police forces, the U.S. Navy Seals, and Delta Force. Built around a straight blowback mechanism with a stamped metal body, the MP uses a telescoping bolt assembly with the main mass of the bolt and the recoil spring assembly positioned above the barrel, keeping the weapon relatively compact. This example was imported by Inter-American for use as a pre-1986 sales sample for soliciting purchases from American agencies. Post front and notch rear sights, with import marks on the barrel, matching numbers on the receiver and trigger housing, electro-penciled matching number on the bolt, three position ambidextrous selector with "E/D/S" (semi/full/safe) markings, ribbed grips, green canvas sling and a side-folding metal buttstock. With a modern soft case and two extra magazines.

Fine as reactivated/refinished (a small touched up area is present on the left side of the frame), with 75% plus matte gray phosphate finish, with a number of light scratches, areas of thinning, high edge wear and some light handling marks. The grips are very good, with mild scuffs. Mechanically excellent.
