A roll film negative. On board the submarine Sealion (1959) towards the end of a long refit at Portsmouth. The photographer is in the commanding officer's cabin between 56 and 58½ stations on the port side of the main flat, looking to port and down from the doorway showing the bed berth with drawers under it. A large locker and a loudspeaker unit are above the berth and a wardrobe and cupboard unit is on the right.
