Did you have 'mirror in the lid' TVs in the
States? Due to the small
defleciton angle, the CRTs in early (1930's) TVs wrre very long from base
to screen. Some mnufactuered stood them vertically with the screen on top
and had a front-silvered mirror in a hinged lid on top of the cabinet.
For viewing you lifted the lid to the 45 degree position and viewed the
refleciton of the screen in the mirror.
(Yes it would be back-to-front compared to what was actualyl on the
screen, but having one of the defleciton coils revesed mant the picutre
you actually saw was the right way round)
Again fully electronic scanning.
My grandparents had a tiny portable one of those. I haven't seen it in
close to 50 years, but I heard that my cousin has it, and he's enough of
an elctronics hobbyist to appreciate it.
