Roundie to identify

A while back I was searching for something unrelated on google images, and I came across this picture of a roundie color tv so I saved it. Anyone know what this thing is?

There is a site dedicated to vintage British/European TV sets where that set is described better. IIRC it was an experimental model that was never sold to the public.

From the picture of the back

looks like a glass tube, probably a 21CYP22?

Yes, the Britts and a number of other countries bought American color CRTs for experimental sets when developing and testing standards.

Think about it, why set up a the expensive equipment for color CRT manufacture when a standard has yet to be established? The BBC did not officially have color broadcasting until 1967 (when that tube would have been sorely antiquated).

This particular set is a purely British creation.

Can you be clearer - do you think they manufactured the picture tube? It's hard to believe they did. The rest of the chassis, yes.

I have seen a few early British 405 line experimental NTSC sets first hand and they used tubes of RCA manufacture.

Created and designed in Europe, some American specialized color parts.
It has both American and European tubes. I recall American
pentagrid ones designed as product detectors (not 100% sure of this.)

another picture...

this is from:

Mike's

http://www.oldtechnology.net/colour4.html

and to quote:

"This next colour set is a 1958 (roughly) Ekco CT100M. I bought it from a great chap called Danny from Norwich for a small fortune, but it is a fantastic set and worth every penny that it cost my Barclaycard. The set is an experimental colour receiver which was originally designed and built as a 405 line NTSC set, but was subsequently factory-converted in 1964 to 625 line NTSC and then again later in 1965 to PAL-S (Simple PAL). The cabinet is very typical of mid 1950s design and there are several different valve lists attached to the back indicating all the different design changes, although they're all stuck on top of one another so it is quite difficult to ascertain any real data regarding the modifications the set has had over the years. I have carried out a fair amount of electrical restoration and the set can now display a half-decent colour picture, but there is still quite a lot to be done to make the picture perfect. I'll post some more information and pictures of this set when I have some."
