Weird and Wonderful

Though it looks like something out of a video game with its twin bayonets, this is a real gun. It is the Sterling S11 sub-machine gun, designed in 1965 as a follow-up to the classic Sterling Mk.4/L2A3 of the 1950s (the latter of which doubled as the Stormtrooper’s blasters in ‘Star Wars’). It was meant to compete with the then-new and now famous Heckler & Koch MP5, and took a few design cues from the equally well-known Israeli Uzi.

Due to falling sales of sub-machine guns in general and to reliability problems with the gun, only one example was ever made; ‘EXP 001′. This was presented to the Ministry of Defence Pattern Room in 1989 and came to the Royal Armouries with the accession of that collection in 2005.

Why two bayonets? One is of the type fitted to the SLR rifle and the other for the previous Sterling SMG. We can’t be sure why the S11 was fitted for both; the trouble Sterling went to suggests that it was intended to give export customers a choice. We can be certain of one thing however; you would never have used both at the same time!
