Hi, Jim.
In looking at your old Ross it appears that the interior parts used to
be blackened to cut reflections. It doesn't look like it would be too
hard to disassemble, clean it and re-treat it to restore the blacking.
I looked up how to blacken brass and was surprised to see Palmolive dish
soap recommended as the way to do it. Says it only takes a few minutes.
