Rare 6 volt Tacho at Swap Meet yesterday

Someone was looking for a 6 volt tacho during the week.. I said they were very Rare & very Pricey.... Well at the swap meet near Windsor yesterday, I saw a nice 5 or 6 inch Tachometer that worked on 6-12-24 Volts... Smiths brand in excellent condition... I didn't get a chance to pick it up... some one bought it for $80,
A steal.... ALSO I saw a reconditioned- Like New, VW push button Radio.. @ $235 a bit expensive, but then I don't want one. I should have gotten his card... I bought a a Pair of BOSCH [as new] driving lights from him for $40 ... Everything He had was like new... He told Me that Valves for the old radios are STILL available.... He had all sorts of Car Radios etc...
