Jonny Casburn was modeler from Iowa (Des Moises I think) and he produced a number of kits, I don’t remember how long he was in business (maybe 10 years or less) but I did manage to meet him at a few contest that were in Iowa. He was a pretty nice guy to talk to. I think Bob Baldus knew him also.
It doesn’t look like anything I ever seen except the Yak Wing & tail feathers, the fuse looks like a Flying Clown but that’s all I see, more than likely, it’s a combination of a few crashed models that he assembled into a flyable model of some kind. I did the same thing with the a Thunderbird and Ringmaster, I called it a Ringleader it flew pretty good and managed to live a long life until I crashed into the bleachers at a football field.
Later,
