Added to the SC 254 Crew Photos set are several images, including the Christmas Dinner photo shown here, and an exceptionally rare view of the Listening Room.

The armory, forward of the radio room, doubled as the Listening Room, in which the hydrophones were operated. The image added to this set shows a sailor operating one of the two hydrophones (The C-Tube hydrophone and the MB-Tube hydrophone), and is possibly the clearest image of this space that I've seen. To the crewman's right is a speaking tube to the pilot house. The two sides of the stethoscope-type earpieces are connected to the two channels, left and right, of the hydrophone. The wheel is used to turn the device.
