Have you reached out to the people mentioned in the Wikipedia article (directors, producers, etc)?

Thanks! I have started to do just that. Including the host, who is still alive.

Yeah I doubt they’d have any copies, but maybe they’d know who to contact. Or maybe see if they remember anyone who was involved with the technical side. Those people might know where archival copies are stored.
