Physical Description

The barrel is made of red wood,perhaps mahogany and consists of six parts which fit very tightly one over the other in exactly the manner shown in the Treatises on the manufacture of service ordnance prepared by the RoyaL Gun Factory in the 1870's and 80's. Each part is marked in black ink with its proper name, again exactly as in the Treatises - the barrel tube itself, 'A TUBE (tough steel)', the breech reinforce, 'Breech Piece (coiled)', the reinforcing collar ahead of the breech piece, :I B COIL', the muzzle-reinforcing tube, 'B TUBE', the heavy outer breech reinforce, with trunnions, 'C COIL', and the cascable screw with breeching loop, 'Cascable'. The components are formed in precisely the way in which they are represented in the Treatises, the only concessions to the fact that this is a model being that the cascable is simply a plain plug, without a thread, that there is no vent, and that the bore of the barrel tube is not rifled.
The number and shape of the reinforcing coils of this model mean that it can represent one of only four types of gun from the many illustrated in the 1879 Treatise on the Manufacture of Service Ordnance: a 7 inch 7 ton MK IV, a 10 inch 18 ton MK II, an 11 inch 25 ton MK II, OR A 12 inch 25 TON mk ii. (See plates XI, XIV, XV and XVI respectively). The ratio of breech diameter to nominal length of the model gun, however, is 3.75 (ie: 11.25 in nominal length divided 3in breech diameter) and of the four guns in the Treatise which are of this construction only one has a comparable ratio; the 10 inch 18 ton gun (nominal length 170.75 in divided breech diameter 45 in = a ratio of 3.8). (The other guns have ratios of 4.54, 3.20 and 3.19 respectively).
The excellent quality of the model and the fact that the lettering on its components is very similar to that which appears in plates in the 1879 Treatise suggests that the model may have been contemporary with this Treaties and used for instructional purposes. The 10 inch 18 ton MK II gun was introduced into service in 1869.
The wooden traversing platform has a sliding top carriage, each bracket of which is cut in its upper edge with five steps. Vertical brass straps at the forward bottom corners support a pair of small brass trucks which just touch the platform. The bottom rear corners of the brackets are cut to receive two smaller trucks and are fitted with axles, but no trucks are present. The forward transom has a curved upper edge to admit the barrel, while the rear transom lies flat to support the quoin bed. The platform has stout rectangular-section side members. At the forward end, between the side members is a D-shaped block pierced with a pivot hole, which is reinforced above and below by two square brass plates secured by four bolts with flat square nuts (one missing). On the underside, a short distance back from the pivot block, is a transom supporting a pair of small brass trucks in line with the side members (and therefore probably for transportation of the platform when away farom its embasure). At the rear of the platform are two stout transoms, the rearmost having bolted to it a flat brass strip, the ends of which step up to accomodate a pair of brass castor-like trucks which are on freely-rotating supports.
The platform and top carriage are equipped with two wooden model handspikes and with a well-made wooden quoin, inlaid on two faaces with a narrow strip of iron. The rear of this quoin is stamped 68.P.95C, which may suggest that (if it belongs to the platform) this carriage was originally built for a model of a 65 pr 95 cwt gun. It is indeed inappropriate for the RML barrel present, which should have an iron carriage.
