This gun is a QF (quick firing) 6-pounder Hotchkiss, a light 2.25 inch (57 mm) naval and coastal defence gun from the late 19th century. The design appears to be pre-1890 as it does not have the recoil system that was introduced at that time. The original 1885 Mk I was a built-up gun with a vertical sliding-block breech. The name comes from the French manufacturing company, Hotchkiss, who were the major supplier of light QF guns in the world. This type of gun became a standard torpedo defence weapon; many navies bought this same type of gun (Friedman 2011).
