This is a Westinghouse 3JP1A CRT complete with housing and shielding.
It was removed from working equipment over 20 years ago and has been
sitting on a shelf ever since. I have no way to test it, so I am
selling it as-is. Would be great for a scope clock or similar! These
had electrostatic deflection, and if I recall correctly the phosphor
is green. The CRT itself, inside the housing, is round, although the
faceplate of the mount makes it look rectangular.
