Fontessa, I'm well aware that the aileron & flap are missing. But as even shown by the red lines, the wing should be tapered. The wing in the pics is not. Also, EACH of the ribs within that section of wing should be progressively smaller towards the wing tip (as should each of the spars), they aren't (notice that the top & bottom surfaces should also be tapering towards each other). With the exception of the three ribs just before the tip, ALL of the ribs are the exact same size. That wing is not from a Ki-106.
Thank you again Fontessa. Looking forward to any information that book brings forth.
This fellow has created absolutely fantastic drawings of the Ki-84, including airfoil shapes.

I forgot to mention before but the Horyuji Temple is truly incredible, it must be preserved at all costs. Thank you Fontessa.
