Be very careful using restored warbirds for reference material, especially where colors and marking are concerned. It has been my experience, and I have been fortunate to have been around many warbird restorations, that the people who do the real thing aren't nearly as picky about authenticity as we modelers are. It used to drive me crazy at CAF, because they thought I was a time waster with my picky questions about why the restorations were painted to suit the aesthetic taste of the particular aircraft sponsor's wealthy wife, rather anything that ever flew in the war. I have seen many B-25 and A-26 restorations, for example, that carry french blue and white, or black and yellow, lizard schemes that never appeared anywhere but in the owner's imagination. Also, most warbirds these days are painted aluminum to simulate NMF, and coated in polyurethane inside and out as a practical matter to keep out corrosion, so don't use flying warbirds for flat and gloss references either. Now "Diamond Lil" I have spent some time in, and once got in on a flight. I used to do sneaky things around the CAF like scratch through layers of paint (in places where it wouldn't show) with a curved X-acto blade to see how many colors had been put on. Diamond Lil, through her various incarnations, has, at least on the inside, been pretty faithfully colored as the original. But remember, she was originally an LB-30, a cargo version of the B-24 and one of the earlier 24's off the line. I think at one time when she was operational she was painted like a nightime Lancaster! Except with those huge American flags on the sides and top. But the natural metal bomb doors were used on B-25s and A-20s, so why not the B-24? A lot, probably most, B-24Ds also carried zinc-chromate wheel wells and landing gear struts. Hope this rambling screed helps a little.
Glad you're feeling better,
