Thanks Matthew, Mark, Gumiflex, Steve, Simon, and Joe !
Matthew - the Kate was also manufactured by Nakajima, and the same cockpit color was used. I have the mixing formula on my build page. The only out-of-bottle color is made by White Ensign Models.
Mark - I've known since before I got the kit that I wouldn't be keeping it. I never saw it as mine, so there's no sadness in parting with it.
Simon - he can say anything he wishes, as long as I get paid.
Joe - you snuck in on me while I was typing my reply (it takes me a while with one finger and lots of corrections !)
Here's a shot of the actual aircraft in flight. You can see that all Japanese aircraft were not chipped like crazy (in fact, very few were).

It's carrying a torpedo with a different tail.
Thanks again !
