A wooden mock-up of the bridge of a Royal Navy destroyer constructed in a shipyard workshop. The ship is possibly a Weapon class vessel and the photographer is looking at the bridge from off the starboard aft corner. The pedestal for the director is on the left. In the rear bridge wing there are a 10 inch and a 20 inch signalling projector with a lookout's position, a compass repeater and a 10 inch signalling projector in the forward wing.
