THIS AUCTION IS FOR 2 RARE VINTAGE CARMEL BUTTERSCOTCH SWIRL CATALIN TUBE RADIO ROUND KNOBS. THESE KNOBS ARE IN BOTH GREAT SHAPE FOR THIER AGE, WITH NO CHIPS OR CRACKS. I AM UNSURE OF WHAT BRAND THEY ARE, BUT THEY WOULD BE A GREAT ADDITION TO ANY CATALIN RADIO THAT IS IN NEED OF A GOOD PAIR OF KNOBS. IF YOU HAVE ANY QUESTIONS, PLEASE LET ME KNOW.
