I don't know why you are turing this into a debate. I never said it wasn't yellow in Europe (and I have that photo in your link); I stated he changed to red in Europe, then added invasion stripes and at one stage added a white stripe on the tail (but no date).... that's all.
I have a book that states he flew a A-51B in Asia, just before being re-assigned to Europe. The book states that the b's never scored a kill in Asia because they were re-assigned England within weeks. It states his squadren joined the 9th who had just received the new P-51c's . I also own a Mustang video showing Howard standing on his left wing with the meatball kill marks being painted on, as the narrator talks about P-51's being tested Asia. And finally, I own Roar of the Tiger and I might be wrong, but I can't see where is states "His first experience with the 51B was in the fall of 1943 in England". The book does state though "he first flew bomber escorts in England in the fall of 1943".
As mentioned war records are sometimes inaccurate, and some comments online or in a book need to be taken with a grain of salt, and who know's you very well maybe correct.. but meh, this is just hobby! All I can say is I'm basing mine off the photos and books I own; whether is is right or wrong, it doesn't mater... what maters is I'm enjoying the build and have enough documentation to enter a scale competition. Peace!
