Any chance of a copy of that? It would be interesting to see.

You can find many examples of old (and not-so-old) test patterns and
idents for British TV here:

I never saw it, but my father built a set in the late 1940s/early 1950s
using a VCR97 tube, which, if I recall correctly, was about 5 inches.

The VCR97 had been a very common CRT in radar sets and was available
cheaply as government surplus at the time. Of course, the resulting
monochrome picture would have been green!
