Need help with Pacific Mercury Model 4321

Look at the date in picture #4: October 10, 1950. The adapter referenced is for the CBS field sequential system which predates the RCA fully electronic system. That's the color system with the color wheel.

I was faintly aware of the pre-NTSC color TVs thanks to the Early Television Museum. So I guess the color attachment looks something like this?
