This is a fine example of a WWII type British MK IV STEN style machine gun that was manufactured using a newly manufactured receiver (tube) from the Charles Erb Company, with some original WWII British/Canadian STEN components along with the new receiver tube as a late model MK V STEN SMG. This model used a fixed walnut buttstock with butt trap, a walnut rear pistol grip and a front walnut vertical foregrip. This model also featured a front sight and front barrel configuration so that a British bayonet could be attached. The underside of the magazine well was originally stamped with "Mk V/146830" and top is stamped with "R.F.I./FR/ M78 /1963". Some of the parts have both British and Canadian proof marks. The new receiver tube is numbered on the left rear side with "E753/9mm" followed by the Charles Erb Bullet Logo. It comes with one 30 round STEN magazine.
