This is an excellent example of a late production pre-war ERMA manufactured EMP 9mm submachine gun. This style of machine gun was actually designed by Henrich Vollmer in the late 1920s and was subsequently manufactured by the Erfurter Werkzeug Machinenfabrik (Erma Werke) factory in the early 1930s. This type of submachine gun was used heavily in the Spanish Civil War from 1936-1938 and was also very popular with early Nazi police and para-military units. The nomenclature for this weapon, "EMP", actually stands for ERMA Machinefabrik-Pistole and was made at the old Erfurt factory in Thurgen. Typical of early German pre-war craftsmanship, it has all machined and blued steel parts. The rear of the receiver is marked with a small single "Eagle N" commercial proof mark along with "EMP/19854". It has the late pattern two position rear sight graduated for 100 and 200 meters. It has the slotted barrel jacket and has the one-piece oak stock with the vertical foregrip. It has the two position (full and semi-automatic) selector switch on right side of the trigger guard and a large safety lever on the right side of the receiver that actually blocks the bolt. The barrel jacket and magazine housing are numbered "19854", and the bolt is numbered "709". It has a blued metal finish with the bright polish bolt. It is complete with one 20 round magazine and an MP40 leather sling.
