Any Between the Lions lost media?

There is not a lot of them, but apparently there is an incomplete WNET promo online with the characters. I remember one person on the site talked about an episode he remembered with disturbing details (positively a huge Mandela effect there), however the forum is now locked as a result.

A lot of PBS lost media is out there, especially promos made exclusively for the local PBS stations and such. For Between the Lions? Not so much.
