This is a fine example a WWII British STEN type submachine gun as manufactured using mostly WWII parts that was assembled onto a new production tube receiver by the Interport Inc. of St. George, Utah. The STEN SMG was the main British submachine gun that was developed and used throughout WWII by the British forces all the way up and into the 1960s, eventually being replaced by the Sterling SMG. They were easy to manufacture, and the British Government produced several thousand during WWII. The overall length of the receiver is approximately 11 3/4 inches long with a short 7 1/2 inch long barrel. The top of the magazine well is stamped "STEN MK II", and the underside was originally stamped "FL 33974/M78". The lower left side of the receiver tube has also been numbered (FL33974) to match the magazine well when it was registered. It has the late pattern "T" style all metal buttstock. The barrel is correctly stamped "INTERPORT ST. GEO, UTAH 9 MM", and it comes with one original 30 round stick magazine.
