I want to remove the plunger from a 1964 Williams San Francisco so I can give it a good cleaning and polishing as part of an overall restoration. The clip that prevents the plunger from pulling all the way through the cabinet does not appear to be an e-clip like I am used to seeing. It also does not have a sleeve on the cabinet side. It is pretty stiff and brittle. I do not know how to remove it without wrecking it. Even if I did manage to remove it, I am unsure that I would be able to put it back in.
Any insights or suggestions on how to proceed?
