Several photos of crewman, probably on submarine chaser SC 284.
First three photos: Thanks to Clayton Rogers for submitting the photo scans to The Subchaser Archives.
Fourth and following photos: MM2 Clyde A. "Cody" Carlson photos, Collection of Thomas Manville Brady, including a rare below-decks shot of crewmen in the crew's quarters. Also a nice leisure time photo of crewmen on the bridge listening to records, one man lounging on the "flag bag" and resting his arm on the machine gun mount.
