If you want to go down the road of a classic Pre-war style electrostatic deflected CRT (using a 5 inch tube, 5BP1 or 5BP4 or any similar scope tube) you could model the set on the Meissner Kit or the Andrea KTE-5, both kits that came out in 1939.
They are very easily adjusted to other scan frequencies and the RF frequencies altered, they can be made to display 405 line video too, with small alterations to the scan circuits and video detector.
The Meissner circuit/assembly manual is here (I found the manual on the net), all common garden valves:

I have restored examples of both of these electrostatic TV sets, the Tech is virtually identical. Here is an article on both:
