Once cleaned, the reflector was about 90% good, so I've decided to use it as-is.
The lens is glass, so it cleaned-up easily in acetone. Not scratches of chips anywere. I wonder if all Radios lights had glass lenses?
The bezel polished up so-so at the bench wheel, but there's some deep pitting on one side. I may try one more pass, but it's never going to be "perfect".
