Actually, no. The standard radar CRT over here at that time was the 
VCR97. That's a 6" diaameter thing with a fairly convex screen. 
(Incidentally, VCR stood for Valve, Cathode Ray, or so I am told).

ObClassiccmp. After the war, there were a lot of VCR97s sold off as 
surplus. And that was the CRT used for the Williams Tube memory on the 
Manchester Mk 1.
