Don garlits brand tachometer on ebay - WOW

That's how collectables go, highest bidder dictates value.
It wouldn't be worth that amount to anyone looking for a quality tach to actually use on a competitive car.
They really were gimmicky cheap crap even when new as toolman states.
Marketing ploy to generate funding for his racing career. He had to collect where he could.
I would bet Don never trusted a single engine that ever won a race to one of these tachs.
Jones would have been a much smarter choice back then. Sox and Martin
endorsed Stewart Warner which they actually used on their racecars.
He was just paid to print his name on them and put his picture on the box.
He will charge you for a autograph to this day. Tires he raced on were sponsored.
Its all part of his gig. A very innovative gig at that to remain on top for so many years.
It is just a cool part of racings marketing history. I could be wrong but it would take a
old photo of one of his dragsters with one of these tachs mounted to convince me otherwise.
