According to the book, the Potez 62 used a modified Clark YH wing profile. I have entered a Clark YH airfoil and used it to generate the wing tip, based on my lofting method. The picture shows the result. In the picture I have overlaid the generated wing tip (green) with the one drawn on the 3-view (red).

The leading part of the wing fits perfectly, while the trailing part is slightly out.  Since the wing tip from the 3-view is wider than the one I generated from the Clark YH airfoil, I will have to modify my airfoil until the wing-tips match. In other words, the wing profile used on the actual Potez 62 was thicker than the standard Clark YH profile at the trailing part of the wing, but otherwise identical.
