CT-100 mumetal shield removal

[dtvmcdonald]

I've obtained a good 15GP22 for my CT-100.

I'm trying to get the mumetal shield of the old, gassy, 15GP22. Its stuck.
One can see some sort of spacers doing the sticking. What are they,
and how does one loosen them? Presumably some sort of solvent?
I don't want to just start trying at random.

Other folks surely have had this problem before.

Trying to slip some sort of tool in looks hopelessly dangerous.
