Scale: 1:36. Sectional model of the 'Caledonia' (1808), a 120 gun three-decker ship of the line. Model is decked and is one of two longitudinal half models which together forms a full hull model. This is the starboard half, which depicts method of construction before Seppings improvements. SLR2908 is the port half and shows vessel after Seppings modifications. Both share the same plaque and original case, which itself divides longitudinally to display the models' internal construction. Plaque inscribed "A model (on 3/8 scale) of a first rate ship of war (such as the "Caledonia" class) The starboard side built upon the old principle of shipbuilding in use up to about 1814, with standards and riders running square from the body and without shelf under the beams or thick water way upon the beams. The port built upon the improved principle introduced by Sir Robert Seppings about 1814 with diagonal wood riders longitudinal and truss pieces, thick water way on the beam and shelf under the beam, truss work between the ports and diagonal deck also showing the round stern and round bow.". Numbers "36" and "39" on original case.
