In 2012 CISMAS undertook an excavation of *HMS Colossus* (wrecked in 1798). This model was made from photographs taken during the excavation in 2012. These were never intended for a 3D model, which is why there are 'ghosts' of photoscales as these were often moved between photos. You can download the excavation report at http://cismas.org.uk/
