Looking forward from the kitchen area, this is the bunks in the forward crew's quarters -- likewise the first photograph I have seen of this compartment.
Behind the pipes is the door to the head.
Photograph of bunks in forward crew's quarters on a submarine chaser. From the collection of George Perley Morse, CO of submarine chaser SC 227. Thanks to E. M. Atwood for submitting the collection to The Subchaser Archives.
