Awesome pics Steve, thank you so much. And while I agree that it does look like the underside color, after studying them longer, I'm still not sure. If you look at the black "walkway" across the wing, almost all paint has been worn off of there exposing the natural metal finish under it. That appears to be the exact same "color" as the center inner flap "color". And also, it looks like a different "color" than the port side strut that would have been the underside color. And looking at that strut, one more thing jumps out at me....it appears to be a different color than the wheel hub, whi
