There was a local auction for some old TV's from the early 50's
recently but this one?. Dunno where you'd get a standards converter
from;?..

on a sort of related note ...You have to start somewhere!
some time in the last millenium (actually around 1982) a work
colleague of mine was trying to build a rCLDomestic
monochrome-to-colour converterrCY from a project published in Wireless
World - a device that converted the signal from an ordinary
monochrome TV so that the picture could be viewed in colour through a rotating optical filter wheel.
The wheel would have had to turn at around 500rpm, and would have to
be 3 times larger than the screen !

You have to start somewhere!Not necessarily. You could mount a lens in front of the screen to
project an inverted image onto a translucent screen. Each colour
would only have to cover the lens. Perhaps six filters in the wheel.
As colour TV came out in 1967, the WW article must be not long after
that. I've now looked at my collection of Wireless Worlds and found a
series of articles starting Sept 1971 describing a sequential colour
TV system using a colour wheel. The wheel is 10" diameter, has only
three filters and rotates at 16 and two thirds Hz. You're meant to
look through the wheel at a 14" b/w CRT, displaying sequential R,G,B
from a special decoder.
