This is a composite of the drawing for Design 26D for the Buckley class destroyer escorts in Measure 33a, originally produced October 24, 1944, which was somewhat late in the process of creating Measure 31-32-33 designs. The vertical colors were: ocean gray (5-O) and light gray (5-L). Design 26D 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. Also, note how the starboard center panel is mis-labeled. There were no known destroyer escorts that used this camouflage.
