Anybody ever seen one of these before? I’d assume so, but still, I was surprised to come across this while searching eBay for timing lights
I personally have not seen this before, nice set. A nice Duel and Tach gauge like this is another thing your going to need along with the timing light. The Duel meter is something your going to need if your going to keep your points in your distributer. The tach and vacuum gauge will help you with setting up the carb.
$500 is out of line for this setup. Offer him $200 which would be top dollar for what it is.
