To the best of my knowledge, there was the P.T. Televisor, the "Argus" from 1952, "A Beginner's T.V. Receiver", there was also "Miniature Portable TV Receiver" (1951/1952) that I think was designed by a teenager, the "Lynx", the 'Supervisor", the 1960 all–valved "Olympic", and the "All–Transistor Olympic", by D.R. Bowman from 1965, then the last b/w design using valves was the "Constructor's 625-line Receiver, Keith Cummins, 1969/1970!
