My box 'o knobs arrived today. It contains a few 40s, 50s and 60s knobs including a partial set of metal SC knobs. They indicate a 'phono' mode - I wonder what set these are from




Here's the "opera Glass" knob back in place. All the metal surfaces on the set have acquired a patina. I wonder if I should leave it as is or try polishing. If I do polish, what should I use ?
