Below decks photos on chasers are rare. My guess is that there are two reasons for this: first, from the perspective of the crewmen, the interesting action was taking place above decks; and second, gasoline fumes created a danger of explosion, so flash photography in enclosed spaces below decks would be inadvisable, any time the engines had been running recently.
There are some compartments that don't seem to be show in any photographs. Others, such as the galley and forward crew's quarters, are shown in a few, but not many; and some areas such as the "Listening Room" -- the armory forward of the radio room, in which the hydrophones were installed -- are shown only in one or two known photos.
This month, in the SC 178 set, several photos are added, including one showing an interesting engine room shot. While most of the images of below-decks rooms show the engine room, this one shows a work area alongside of the engines, which is unusual.
