All of these have since sold. All of the Buchons (reportedly 9 airframes in total, including the two-seat variant) and the Spitfire are headed to Europe for restoration to fly, while the Mustang is staying in the U.S. with its new owner, for eventual restoration to fly. One of the Buchons was wheeled out a month back, and started-up on the first try!
Besides the aircraft, Connie Edwards does have a lot of 'stuff'. Numerous Merlin engines, P-51 cowls and canopies and other parts (at one time, he owned at least a dozen P-51D's (1970's/80's), all of which have since been sold to various owners and restored over the years, except for the last one he held onto). In the climate where he's located, the chance of corrosion is nill, so these aircraft have fared incredibly well in Connie Edwards care over the last 40+ years.
