The drawing for Design 32/6T for the President Jackson class attack cargo ships using the (C3 P & C) maritime hull dated January 10, 1944. This drawing specified the Measure 32 vertical colors: light gray (5-L), ocean gray (5-O) and dull black (BK) with the horizontal color of deck blue (20-B).
The only other drawing for Design 6T was also for the President Jackson class and almost identical except it was Measure 33 using pale gray (5-P) and ocean gray (5-O) probably drawn at the same time.
