Model of a Caisson in its Bed, Truss model of a ship's door with double keel, placed in the frames of a dry dock. The ship's door is completely finished on one side and open on the other. Parts of the three decks connected by stairs can be removed, within a division into compartments. Two small scuppers at the bottom on the closed side, their operation is unclear, but seems to happen with wedge-shaped valves. Only one pump on each side. The opening of the dry dock has three rebates, so that the ship's door can be put in two places., anonymous, 1800, wood (plant material), brass (alloy), h 19.5 cm × w 40 cm × d 18 cm
