I wasn't 100% sure about the Falcon mentioned, so--- I texted Gail Brock for the answer.
"It was his personal vehicle. It's called a Ford Sedan Delivery. Peter ordered it special with a V8, which meant it had to be moved from the regular production line to a different line that installed V8's. As far as Peter knows, it was the only one built that way. He doesn't recall when he sold it, but the person he sold it to was the person who sold it to the museum in boulder."
