Originally developed by Heinrich Vollmer for ERMA as the EMP, the VPK was a variant employed by Francoist Spain, the chief modification being the elimination of the ventilated barrel shroud to reduce weight. Blade front and tangent adjustable notch rear sights, with "BSI" on top of the magazine well, "VPK/628" on the endcap, and matching numbers on the barrel, magazine well, receiver, endcap and the interior of the stock. A two-position selector switch is mounted to the right side of the trigger assembly, with a takedown lever behind the trigger guard and a telescoping monopod built into the forward pistol grip. Fitted with a smooth pistol grip stock and a brown leather sling. Magazine absent.
Fine, with 60% of the original blue finish, with a dark brown patina concentrated on the barrel, mild handling marks and scattered spotting. A few patches of bright metal are present on the underside of the receiver, possibly from chemical exposure, and a few areas of deep pitting are scattered about. The bolt is mixed numbered. The otherwise fine stock shows a number of light scuffs, dents and stains. The magazine catch is absent, otherwise mechanically very good.
