Physical Description

A model in bronze of an iron 68pdr shell gun of 95cwt., being a Dundas design of 1864. The gun resembles No.189 in appearance, the only differences being a slightly longer vent patch and the absence of a dispart patch at the muzzle. The left trunnion is stamped R.G.F. (Royal Gun Factory) and the right No.5. All markings on the reinforce have been obliterated with the exception of a Broad Arrow. Cf. No.188.

The gun is mounted on a wooden sliding carriage placed on a dwarf wooden traversing platform. The dwarf platform was lower in height than the common traversing platform, enabling the gun to be fired either through ordinary embrasures or over the top of parapets, while presenting less of a target to the enemy. The carriage resembles a rear chock carriage but has a wooden block at the front instead of an axle and trucks. A small truck or roller is bolted to the front of each bracket to facilitate running up when the rear of the carriage has been raised by means of truck levers. The platform consists of two sides joined by three transomes; their upper surfaces are reinforced with metal plates to ease the working of the carriage. The bollard for the preventer rope to check the gun when running up is fitted on the inner face of the left side member, at the rear. There are two pairs of trucks, a small pair at the front and a larger pair at the rear, which give the platform a slope of 5 degrees; the rear trucks swivel to follow the curve of the rail

Inspector of Artillery and of the Royal Brass Foundry 1839-52. His 68pdr gun introduced c.1840, is the 10ft long model shown in Adye's 1854 list (App.II). It was described by Sir Howard Douglas in 1851 as 'one of the most valuable guns in the service' ('Naval Gunnery,' 3rd edn, 219).
