This drawing shows how the drawing for Measure 31 Design 3D for the Gleaves
(DD-423) sub-class of the Benson
class as dated June 5, 1944, might have been used to create a new drawing 31/3D (reversed) by simply flipping the original to reverse port and starboard.
The vertical colors of the original were specified to be dull black (BK), ocean gray (5-O) and haze gray (5-H) and the horizontal colors were ocean gray (5-O) and deck blue (20-B). Light gray (5-L) could have been used in place of haze gray to be Measure 32.
I have identified this as 3D rev
(reversed) even though there seem to be no USN drawings that would depict this.
