At any rate, there remains a lot of confusion about this machine:
1) I've always seen her specified as being blue gray over light gray. The book indicates that she had been repainted in tricolor, with the lower wing surfaces possibly left in blue gray. However the images here don't seem to support the use of tricolor, and certainly the nose art panel salvaged for
Ramblin' Wreck suggests she still had blue gray (or else EXTREMELY faded) upper surfaces.

It's inconclusive from this image whether she's actually white underneath.

This one suggests that she could be white underneath, but it could also be the result of shadows.
Most recently, I've seen it suggested that at least parts of the wing uppers were touched up with the standard semi-gloss sea blue. The images here are inconclusive, as it's difficult to tell what's paint and what's mud (though it looks like the leading edge, and parts of the middle of the wings may be darker than the rest of the fuselage).
2) The demarcation line has numerous interpretations, as well. Historically, she's been depicted as blue gray over light-gray, with a very high demarcation line. This book attributes the same to an unusually high intermediate blue middle band. However I've ALSO seen where this unusual color pattern is described as the result of a large and very light exhaust stain.
3) Some profiles suggests this aircraft had a light gray stabilizer (on a blue-gray aircraft) which would be VERY unusual for a blue gray over light gray bird, as the stabilizer was usually done in the same blue gray as the uppers. Unfortunately it's pretty mangled in the existing photos, but some do suggest the stabilizer was significantly lighter than the rest of the uppers (which does support her having been repainted in tricolor).
