Below I compare the 2 versions of the face in question that I have (RPPC left, dot matrix print center), both giving a pretty good sense of the shape of this guy's visible ear.
Comparing these to a Wilkinson exemplar taken at virtually the same angle (far right) the difference in ear shape as seen from the front, the amount that he ear sticks out and the angle of the ear with respect to the head is clear and substantial. It is essentially impossible for this guy to be Wilkinson.
There's another facial thing that is equally damning to the Wilkinson claim, but I'll save it for a future article.
