If you find him, see if you can find out what specific issue of Asahigraph it is in.
Got a reply on the skin from Ron Cole he sent me a email & here it is.
Rodney,
Well, nice to hear from you! Interesting to learn about interest in the Japanese P-40. Some time ago I had a deal where I gave away a signed print of that aircraft to everyone who built a scale model of it.
Those Asahigraph photos came from a friend in Japan who collects such things. I only know that the accompanying captions described that the aircraft was captured in the Philippines and depicted American crew being forced to train the Japanese in its operation. Since then I've learned elsewhere that the aircraft was one of several P-40s that were brought to the Philippines by blockade runners and actually arrived in early 1942, and that the shark's mouth scheme was painted by its crew to "emulate the Flying Tigers" of China.
I have no other information.
I actually have that other shot as well, but might not have included it on my site (I accidentally saved them in different folders on my drive). Thank you, though!
All the best,
Ron Cole
