Valdi,
I'm pretty sure that USS WILSON (DD-408) transferred from the Atlantic to the Pacific in 1942 painted in Ms 12R(mod). But, I don't have any photos nor seen any that show what pattern she had. I pulled 80-GK-00435 at NARA and after looking at the 2.5x3.5-in copy negative from a transparency that NARA has, I didn't bother scanning it because it was way too dark. The original color transparency "MAY"(?) have allowed for some image details to be pulled out, but the transparency is either lost or is long gone. This transparency was among a group of color images taken by a photographer onboard USS WASP (CV-7) on her Task Force passage to Tongatabu, so was taken during early July 1942 (not August 1942, since it appears the photographer and his color film left at Tongatabu), before USS WASP arrived at Tongatabu on 18 July 1942.
Chuck Haberlein had a color print made of this image and the scan he made from that still had some color. When NHHC decided to re-scan their collection, many of the poor quality color images were simply scanned in grayscale.
Here is a copy of the "color" version that Chuck posted on his old website;
I had played with this image some time ago, but can't find it. So, I played with it again and here is what an "adjusted" image trying to show any pattern. It sort of looks like there "may be" a pattern there, but it certainly isn't clear what the whole portside looked like.
As for seeing evidence of the Ms 12R(mod) pattern on USS WILSON in the December 1942 MINY photos, be careful on what you are assuming is part of the pattern. First off, it was common practice to leave painting of a ship during yard periods until one of the last tasks done. Also, it was routine to take a ship out for a "test drive" before releasing the ship for departure and operational duty. So, this sequence of photos at MINY probably show her going out on a trial to see if everything is working at least well enough for her to go for "new configuration" shakedown and training with her new 40-mm armament and SG radar. Some of the "lighter" areas is primer paint, specifically the front of mount 51 shield and part of mount 52 shield.
Another question, is did USS WILSON have time to repaint to Ms 21 or at least repaint the hull with 5-N paint? The order went out in October 1942 for units that transferred from the Atlantic needed to apply Ms 21 "ASAP within operational needs". This is a case of a ship that lacks photos during this period and unless some long lost photo turns up, it may well remain a mystery.
