Thank you all for the kind replies regarding the resoration!
I'll try to answer a few of the questions.
Eckhard, I did not take a photo of the wheel but it is just 6 segments of filter material glued together. It is not a rigid wheel but rather quite "floppy" as you could not stand it on end.
The converter converts NTSC to field sequential. The sync pulse is taken off the vertical and the converter knows what color is in front of the CRT from a mechanical commutator at the hub of the wheel. BTW, that arrangement causes a lot of noise in the picture.
Julian, don't confuse this with the CBS sets at ETF. This wheel runs at 600 rpm whereas CBS is over 1400 rpm. There is considerable flicker in the Col-R-Tel picture and fast movement causes the color to break up. That can even happen when the viewer blinks!
