Update:  We now believe the mystery photo was very likely taken at Keesler AFB, MS, where radar troops went for basic electronics training before being assigned to the various radar stations.  The old WW-II barracks were still used in the 1950s (and 1960s) when the photographer was there.  This photo probably got mixed in with his photos of Makah AFS, WA.
