All I can tell you is there are a few dozen plastic bins of gun assemblies at the museum in Ohio. Color vs. B&W, neck diameter, filament voltage/current I could not say.
Also, I opened a few bins and the contents were not promising. Some of the plastic bags the guns come it were open to the air. Many had loose powder in the bags. I think it was the getter material that had fallen out of the getter cup.
Now I ony looked in 3 or 4 bins. There are many more that may have better gun assemblies.
As for flare neck glass tubes. There was one full box of the diameter for something like a 10BP4. There remaining 20 or so boxes seemed to all be smaller diameter for newer CRTs. Like the 21FDP4 used in Predictas.
