Oldest surviving quad videos?

[Aussie Bloke]

G'day all.

I've recently viewed a valuable information resource featured on the ETF site listing the earliest surviving kinescope recordings of television programs http://www.earlytelevision.org/image...rigins.pdf.pdf and whilst I was very happy to see all the info on the early kinescopes and audio recordings I was a bit disappointed there was no mentioning of the earliest known surviving quad videotape recordings from the 50s. So I was wondering if such a list has been made for the earliest known surviving B&W and colour quad video recordings from say 1956-1959 for B&W and 1958 to 1962 for colour? I am really interested to know more of what has survived than what I have already found out browsing the UCLA site and Quadvideotapegroup site and YouTube.
