Hello JH,
You have inadvertently answered a question that came up at our Oshkosh campsite: "I wonder who is the proud new owner of Mike Wilson's PT-22?"
Mike and his gorgeous Ryan made up a very large portion of a very small Warbirds community here in Cedar Rapids, Iowa.
I am attaching a picture of my one and only Warbirds ride from the front cockpit of your Ryan. It is of dubious quality taken some 30+ years ago on a rainy day at the Blakesburg Fly-In and I simply squared my instamatic behind my head and snapped the picture. You can make out Mike's big grin.
It was one of two times that I had the chance to fly with Mike, the second time in Mike's Bonzana. Having been a flight instructor in WW II, Mike talked us through everything he was doing as he took off, set up his approach and landed. We talked about his PT-22 and, in that day and age before the Internet, my mom asked him what sort of resources were available to him to help him maintain a PT-22. His reply was simple and direct: "I
AM the resource on PT-22's!"
I can't answer your question about nose colors but I will add during the time period that USAAC birds wore the red and white rudder stripes the insignias on the wings would have carried the center red dot. As we know, regulations aren't always followed and there are numerous documented examples of birds wearing a variety of markings during times of cross over. I do not wish to imply the markings are "wrong" by any means. As for your missing lifting eye, you might contact the folks at Blakesburg.
