FROM WIKIPEDIA

The MP34 is a submachine gun (SMG) that was manufactured by Waffenfabrik Steyr as Steyr-Solothurn S1-100 and used by the Austrian Army and Austrian Gendarmerie and subsequently by units of the German Army and the Waffen-SS in World War II. An exceptionally well-made weapon, it was used by some forces well into the 1970s.
