I have a couple of sets for the radio, one set is in excellent condition. The other set has very light pitting on one of the outer knobs. I have three cigarette lighters . One has excellent chrome, one has light pitting. The third has spots where the chrome has come off, but no pitting. I had to really look hard to see that some of the chrome has come off. The elements on all three most likely don't work.
