Gathering data on CRT rebuild value

[Geoff Bourquin]

Regarding h/k assemblies for rebuilding old guns, it appears they are in very limited supply. Does anyone know if it might be possible to use h/k's from modern CRTs? It has been pointed out that there are guns available for modern tubes but nobody has any use for them. Would it be possible to remove the heater/cathodes from these guns and mount them in place of expired ones on vintage guns? I realize this is a long shot, but it never hurts to toss out an idea. Worst thing that happens if everyone laughs at the dumb guy, right?
Another thought, what about getting guns from Asia? I understand someone is still making CRTs for use in some parts of the world. Maybe a they could make a supply of guns for our old B&W tubes. (I know..probably even dumber, and expensive idea)
