Col-R-Tel was a commercially made unit, ready to connect to your B&W TV.
That is one in my avatar.
Colordaptor was a magazine article with a set of instructions and some major parts available from the designers. This was in 1956.

P.M. me and I'll email you all the info I have on both types.

As I've said before, the color electronics part is easy. The wheel part is not.
I have built 5 wheel sets in the last 6 years. The motors are different for each one based on the speed and size of the wheel, and the servo circuitry for each one is also different.
If you build a wheel set, you will see what I mean. The servo circuit is more difficult to make work than the color circuitry is.
