Or three B&W CRTs, each with it's own filter, and a "beam-splitter"

That's no _A_ B&W CRT. It's 3 of them

I suppsoe you could divde the screen of a single CRT into 3 sections. Put
diffent filters over each scetion, and then combine them into a single
image usign the 'reverse beamsplitter'. That's _A- B&W CRT displaying a
colour image.
(reversed to combine) in a projection system (~1970
projection TV)
Rhater later than that over here. I remember such sets (back projection
onto a large-ish scren) in the 1990s here.
