Just watched the video and what can I say, WOW!!!
I wonder if that very first set on the way in the first warehouse is a 1956 RCA CTC-5? Anyhow I sincerely hope a lot of the sets were saved by collectors/restorers.
If those warehouses were down here in Australia and I was going through it, I would go nuts, there would certainly be a different range of TV sets that's for sure in which all the 50s/60s ones would be B&W and of brands like Astor, AWA, Healing, HMV, Philips, PYE, Kriesler etc. and the colour ones would be from the 70s/80s which would be Thorn, Philips, Kriesler, PYE, Rank Arena etc... My mate John of
