there was an outfit near or in Philly that would cut the neck off of yer

Normally it was the other way round. You kept the
screen/phosphors/shaddowmask, etc and replaced the electron gun (either
the whole thing, or just the heater/cathode part, depending on the CRT
type). It was a way of getting CRTs that had lost emission (i.e. worn-out
cathode) going again.
Did they typically replace the damage with a new section from the factory
(i.e. manufacturers were happy to supply 'bits' of a CRT) - or would the
repairers find a donor tube and salvage the sections that they needed?
You could buy them new, at least as recently as the mid-90s. The gun
looked pretty much as you'd expect - a flat glass disc with a long glass
tube sticking out between the pins, and the gun assembly exposed. Some
had about 2" of "neck" around the gun, presumably because you needed to
weld the glass differently.
