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.

getter material + air = BAD!
