Scale: 1:60. A contemporary full hull plank on frame model of a 51-gun steam frigate (1857) fully equipped on deck, together with a complete set of boats both in the waist and rigged to the yard by tackles and davits. It is fully rigged including a main topsail and the inner jib on the bowsprit.

Although the model has not been positively identified, the measurements of 235 feet along the gun deck by 50 feet in the beam, agree with a class of four steam frigates built from 1855-60, the ‘Shannon’, ‘Liffey’, ‘Topaz’, and ‘Liverpool’. The model is fitted with a Smith screw propeller, which can be raised or lowered in an iron frame, as well as a funnel amidships hence the term ‘up funnel down screw’. The planking on the starboard side has been partially omitted to show the internal construction of the frames and layout of the lower decks.
