The glass master who made the film, as far as I can tell, is still working today. From his comments, it seems that he doesn't want to deal with CRT. Pyrex glass tubes and Pyrex glass are still available. So you can experiment with this glass today before you touch an old CRT. I think the main problem today is finding a suitable electron gun to replace - which is unlikely, or a working H/C assembly to replace from another CRT - which is more likely. The question arises whether an air-filled cathode from a good CRT will work in a new CRT. How long can it take from removing a good activated cathode from one CRT to inserting it into another and obtaining a vacuum again. Does such a time exist? In the era when CRT regeneration consisted of replacing the electron gun with the same one with a pumping tube, this was not a problem. Today, you can't reach for such a gun on the shelf. Glass connections can be obtained today by various methods, without using high temperatures.
