I too have seen that collection and it is amazing what he has. Looks like CE is selling everything off.

The Mustangs did not come by way of the movie. They are ex-Nicarauguan AF Mustangs that he and his brother bought and ferried back to TX. There were a total of six IIRC. They and some friends flew them up to OSH in as found condition for the annual airshow in July. Funny - they used plastic Schlitz beer cups as exhaust stack covers. When they fired up to head back to TX, they left the cups in there and when the engine fired up, it popped all the cups out to the ground. Caused a big laugh. Shortly after, his brother was killed in one of the Mustangs and he just parked them. Twenty something years later he decided to sell two to fund some business project. One went to a Swiss collector and one went to my father and a partner. That is Miss Marilyn today in Houston I think.
Sad to hear about his son. Good guy and a hell of a pilot. Soloed on his sixteenth birthday a bunch of airplanes - T6, Twin Beech, Super Cub, Stearman. I only met him once at one of our formation gatherings.
