Unless you get a specific Tuskegee kit, Tamiya D or Accurate Miniatures B/C, You will have to go after market. Actually if you go the Tamiya route you will need after market decals anyway because the Tamiya decals are not very good.
I have just completed the Tamiya kit as Bunnie. It was a good kit except for the thick decals. Previous to that I completed P-51B hacked with the D style canopy, 43-12102. I am now working on P-51B Hun Hunter, the Accurate Miniatures B/C Tuskegee kit.
Both B and D kits that I used for 43-12102 were Revell kits. I found the Revel kits to be just as good as the Tamiya and AM kits. There is some accuracy problems with the AM wings.
I am trying to post a photo of the D and B/D in flight???
