Classic TV: The 50s : "The Birds" episode from DANGER!

"The Birds" episode from DANGER!

For years I have been looking for a video of the final episode of the TV series DANGER! It was an adaptation of "The Birds" by Daphne du Maurier.
I've tried everywhere, including the Museum of Broadcasting. No luck.
Is there someone out there who has a copy or a fresh idea where to inquire?
