I can add the inboard tail letter and numbers, the "I" on the wing and the fuselage "IO" code. Its just that without sufficient info to back it up HTC might object to the skin's authenticity. Do you have a photo of an OD B-24 with the yellow and black tail and the codes inboard, or a 715th BS aircraft with the "IO" codes on the fuselage?
I've also noticed that they greyed out the white in the stars and bars insignias so I'll change that too.
