Hello, Ron: I have a question after looking at your excellent "phantom" model 97 chassis: How do you clean your tube shields? I have several of the square variety that are pretty rusted......
I've been going over them with a wire cup brush attached to a Dremel tool, then spraying them with Krylon Satin Nickel paint.
A few guys are having them replated with tin. This is how they were originally done - plated with a thin coat of tin which wears off over the years.
