I have a few comments to make about what I've read on this subject.
1. Note that "Cripes A Mighty 3" was an early D model P-51. The verticle stabilizer doesn't have the classic fairing. In other words the tail looks like that of the B and C models. So unless Trumpeter has an option for this on their kit be prepared to modify the tail. "Cripes A Mighty" 4 was a D model like the Trumpeter kit.
2. I haven't seen any decals for 332nd FG (Tuskegee Airmen) yet. There are some starting to come out. I haven't seen too many photos. But there is some good art work out there. The color schemes on these aircraft are pretty basic and there isn't a lot of nose art to worry about. If you're good with masking and painting you should have no trouble producing a 332nd FG P-51D. The toughest part might be some of the paint work around the nose. I have John Shaw's print hanging with pride in my office. It's a beautiful airplane signed by great American's. Anyway, here are some links that might help you...

3. I would swear that I received an add from Meteor saying that they had a line of 1/24 decals for the Trumpeter kit. Maybe I'm wrong though. Eagle Strike has a set of Blue Nose Bastard's of Bodney in 1/24th out. Here's a link for that...

Have fun guys. Looks like a great kit! I'm hanging on for the F4U and P-40B/C kits they are planning on releasing later this year.
