CT-100 mumetal shield removal

I will leave it for others to respond to your question. I’ll just say congratulations on finding a good 15GP22.

Not sure if the Westinghouse setup is the same, but on that one it really is only a few rubber spacers around the small end on the inside of the mumetal shield. They seemed to be only stuck due to age and not any kind of adhesive. Mine came off with only a small amount of force. The CRT and shield seem to be a pair since they were both marked with the same handwritten four digit number.
