USS Hector (AR-7) repairing the torpedoed USS Houston (CL-81) at Ulithi on November 1, 1944, wearing camouflage 32/4Ax. Houston is in camouflage 32/1D. Photo taken from USS Essex (CV-9). Photo source: NARA 80-G-373678.
AR-7 was sent 32/2Ax (sic), on 1/26/44 which may have been a typo, since later on 6/1/44 she tasked Pearl Harbor to paint her in 32/4AX.
