USS Thatcher (DD-514) again on February 7, 1944, outside of Mare Island. The lower contrast between the ocean gray and the lighter color confirms that it is haze gray. Notice the extra stripe on the stern quarter. Photo source: NARA BS 61381.
USS Thatcher (DD-514) shown on February 5, 1944 at Mare Island, matching the drawing for 31/2C very well. The deck pattern is clearly visible. The white dots are holes punched in the print and the circles are on the copy negative to indicate modifications made at the yard. Photo source: NARA BS 61379.
