One thing, just about all the expensive vacuum tubes for industriall, broadcast and medical use are sold thru one company.
That is Richardson Electronics. They now have offices over the world.

I could only get one of the links to work.
The sales in this category are now down to $325 million. Sometimes the
data that is captured in these analyses may not exactly match our
perceptions of these products.
Perhaps there is a market for high power tubes to be used in
broadcasting applications world wide. There may be a substantial market
for tubes used in medical and to a lesser extent, scientific/commercial
x-ray machines and CT scanners. I heard a rumor that some of the x-ray
tubes for CT scanners start at $10,000. Perhaps some specialized tubes
are still being produced for radar use or high power RF ovens.
The category of vapor or gas filled tubes might include various types of
mercury or sodium filled lamps used for lighting etc. Some special
mercury tubes are used for UV germ killing.
Out of all of this there probably isn't $1.00's worth of stuff for
