If you (or anyone else) is interested, I have a few of the b/w cocktail
GO-5 tubes but with *green* phosphor for $33 each. Never used. They came
out of some computer terminal system that was never installed. Just a
bare tube. No yoke or magnets.

FWIW Aligning a b/w tube is a no-brainer compared to a color tube. No
wacky shadow mask to make things difficult. Just take lots of
measurements and make lots of alignment marks on the tubes, magnets &
yokes so everything lines up like it did on the original tube.
