When I was a kid living out in the woods with my grandfather the AG at Charleston, WV just got the P-51's after the war. On Sundays there would be a string of 51's coming from the south and making passes on a knoll about 1 mile north. Good airshow every nice Sunday. Still in love with P-51's
On my first job out of high school my boss was a Flying Tiger and then flew P-51's in the war. We always ate lunch together and he would tell me his war stories.

Did someone ask what the Airfoil is?
TIA

Yes. Separate thread. Turns out this is a very nice airfoil, based on the analysis of an aeronautical engineer friend of mine.

It does not hit a "brick wall", or speed-brake, as does the standard wing.

This from my aeronautical engineer buddy:

The airfoil on your wing, from what I see, has a reflexed UPPER surface toward the TE. The 6-Series are early attempts at controlled pressure recovery on the upper surface, and are more noted for having under-camber toward the TE so as to drive more camber aft into the TE of the section. I've certainly not seen them ALL, but this doesn't appear to be a NACA 6 series shape.

Nor does it resemble Riblett - from what I did study of his work (mostly in the "GA" series he did) they look very close to 6-series. Harry did seem to improve on the 6-Series, though - he never was regarded as a true "professional" aerodynamicist by those who do work in an aero-science capacity either for the Govm't or some major airframer.

The section I see here resembles more of some of the work Richard Eppler did, in some of his "low reynolds number" airfoil applications. Attempting to maintain laminar flow well back in the section with max thickness and camber pretty far aft.
