A composite of the drawings for 33a/26D for the John C. Butler class destroyer escorts dated October 18, 1944. The vertical colors were ocean gray (5-O) and light gray (5-L) while the horizontal surfaces were solid deck blue (20-B) with no pattern. Design 26D was issued somewhat late in the process of creating Measure 31-32-33 designs. It also shows clear influence from the earlier Design 22D; so much so that, from the starboard side, ships in this design could easily be mistaken for 22D, while the port side differed by quite a lot.
Original drawing sources: NARA 80-G-104895 and 80-G-104896.
