I fear that N2IXK paints an accurate picture. Some parts aren't quite so bleak. Glassblowing skills are likely to exist for the foreseeable future. Glass to metal seals are also likely to stay aroiund. Some vacuum devices, such as photomultipliers, are still made in significant quantities, mainly for scientific research. I don't think Hamamatsu are ceasing production any time soon. Hot cathodes are still used but in specialist devices and small quantities.
Bringing all that together in the right form for making CRTs is another matter. Also there is little or no hope of making pressed (as against blown) CRTs from scratch as the tooling would be hugely expensive. All rectangular CRTs are pressed as were the later round ones.
In the US, Ebeam and Thomas still exist but I don't think either is interested in our business. In the UK there's a company near London who I've spoken to. They are confident about being able to make blown CRT envelopes, can also do the glass/metal seals, but have no gun capability at all. Also in the UK Brimar (not sure how related they are to the original Brimar compnay) are still refurbing military and avionic CRTs. I don't think they're interested in us either.
That leaves the excellent work being done at ETF and the German company whose cpabilities are currenty being explored.

The arts of CRT making aren't quite dead yet.
