One of the signature Commonwealth weapons of WWII, the STEN was largely constructed from tube steel and metal stampings, a significant departure from the previous generation of beautiful but expensive SMGs, giving the Allies a light, effective, and inexpensive close-quarters weapon. Blade front and peep rear sights, with the model marking on top of the magazine well and "H.F & CO. LTD" and the serial number on the underside, with a full black finish, "R" and "A" marked selector switch on the trigger group and a half-tubular fixed buttstock. Inter-American's import marking is present on the underside of the tube. Magazine absent.
