This is a highly desirable Vickers Pattern Mk I heavy machine gun that has been assembled on a Charles Erb sideplate. An evolution of the Maxim Gun, the Vickers was a well refined heavy machine gun, with a water cooling system that permitted long strings of automatic fire without overheating. Blade front and folding peep rear sight on the top cover and a Mark II dial sight mounted on the left, which conceals the Erb markings. The water jacket is brass with steel endcaps, with a "303" marked feed mechanism and a set of smooth wood spade grips. With a steel and brass tripod, a petrol can, and a belt box containing three canvas belts, tool and two oilers.

Fine as assembled, retains 95% refinished blue finish with a few areas of light pitting visible underneath the finish and some scattered light handling marks. The spade grips show mild scuffs, and the accessories are in good order. The rear spade grip is retained by two incorrect length shorter bolts, otherwise functions mechanically fine.
