Dennis,
Thanks for the the excellent picture of Jim. If that airplane has a conventional landing gear it is the airplane that I flew. Bob Hunt had told me the it is named the "Spirit of America"
As to Classic eligibility: I am proud to say that when I was the PAMPA District 2 VP, before moving to Texas I was instrumental in having the "Classic" eligibility changed to to include "reasonable proof", such as photos, magazine pictures, etc.
There is a very important reason for this. During the "Classic" appearance requirements included "originality" This contributed to the rapid development of stunters, and many very good modified and new designs. Every area of the US, and for that matter of the world, had winning designs that should be seen again.
As a result of "reasonable proof" being added, we have more recently seen the Flying Models "Classic Series" , "Classics" published elsewhere. This allowed us to have airplanes like "Ballerina III" (FM), "Jerseyan" (MA), Kostecky's "Patriot" (FM), Billy's "' '61 Ares" , and more available to all of us.
I had Artie Meyers's "60 NATS Sr. Stunt winner, "New Yorker" in my possession until I moved to Dallas. I have the original pencil drawing, and I took about 70 pictures. I also have pictures taken when the airplane was flown in 1960. This certainly is a future article, that Bob Hunt and I have discussed.
Thankfully these airplanes are eligible, due to "reasonable proof", they deserve to be seen again.
I had sent a copy of a magazine article on the '69 team trials, to Big Art several years ago that includes your "Typhoon" and and other "Adamison" airplanes. I can send you a copy if you like. This is certainly "reasonable proof".
YES, there are many "Adamison" airplanes eligible for "Classic Stunt", along with many more designs, I am sure.
