What was the upshot of the 1st Shelby Museum (Rick Nagel) --not the one in Boulder

I was reading a GT40 site today

GT40s.com


about someone rebuilding a J-car and they said they bought some mechanical parts from Rick Nagel. I know there's a Shelby Museum in Boulder that is the present day Shelby Museum but whatever happened to that first one in Texas? Weren't they the recipient of several GT40s and J-cars? I know museums are allowed to sell what they are donated (I can't pronounce the word but it's something like de-accession) but did Nagel end up making a bundle on all the stuff he was given? Did all this reach the courts?

PS No connectionn with the Mustang Museum which I guess never got off the ground
