The photographer is in the aft torpedo compartment at 109 station on the starboard side of the main flat looking to port showing a stainless steel sink with a sign reading "5. S.E.I.S. below" and lockers under it. S.E.I.S. stands for submarine escape immersion suit. Lockers are next to the sink with stowage space for a Bidder torpedo below them. A notice on the locker states "Lockers to be removed for escape." A vertical format negative.
