A spiritual descendant of the World War I Bergmann MP18 SMG, the MP34 was developed and prototyped by Solothurn in Switzerland and manufactured by Steyr in Austria; restricted from SMG development by the terms of the Versailles Treaty, Rheinmetall of Germany bought stakes in both companies to get around the rules. A fine piece of craftsmanship, the MP34 is a fine exemplar of the final generation of hand-fitted, precisely machined sub-machine guns, which would give way to the mass-manufactured, machine stamped, utilitarian lines of the Sten, MP40 and their descendants. This example has been deactivated by having a steel plug inserted into the breech and the face of the bolt ground off smooth; the bolt is not welded to the breech, and the bolt can be cycled in both semi-auto and full-auto modes. Blade front and 500 yard tangent rear sights, with a bayonet lug mounted on the ventilated heat shield and an "E" and "D" marked selector switch on the left side of the stock. An Austrian "eagle 34" proofmark is present on the left side of the receiver, with matching numbers on the receiver, bolt and stock Fitted with a smooth one piece stock with a serrated steel buttplate. Magazine absent.

Good as deactivated, with 60% of the blue finish overall, showing areas of rust, pitting, and scuffing. The stock is fair, with cracks, chips and dents. The magazine catch for the clip guide is missing a spring, and the arm is deactivated as described above, otherwise mechanically fair.
