A 2¾ x 2¼ film negative. On board the Type 12 frigate Yarmouth (1959) alongside the South-West Wall in Portsmouth Dockyard. Inside the C.C.R. (RX) on the port side of 2 deck between 25 and 28 stations looking forward from the aft end of the compartment. An operator's position is on the left and a large floor mounted receiver unit is on the forward bulkhead. Stacks of electrical cabinets line the inboard bulkhead on the right. The meaning of the initials C.C.R. is not known but (RX) almost certainly refers to reception. The plans in the Admiralty collection use these initials instead of words. A vertical format image.
