On board the submarine Walrus (1959) alongside the fitting out berth at Scott's Shipbuilding & Engineering Co Ltd shipyard at Greenock, on the Clyde. The photographer is in the junior rates mess in the forward accommodation between 34 and 44 stations on the main flat looking forward and to port showing two triple tier bunk units against the boat's side with drop leaf tables and locker seats in the foreground. An amplifier cabinet and a battery compartment intake trunk are in the port forward corner. The watertight door in the bulkhead at 34 station is open.
