A roll film negative. On board the submarine Sealion (1959) towards the end of a long refit at Portsmouth. The photographer is in the forward torpedo compartment looking slightly aft and down into the coxswain's store on the starboard side at 32 station. Shelving is on the forward and the aft bulkheads of the store and a cover is over the crosshead raise and lower gear in the centre of the store.
