Vintage Sun Super Tach. Why are they worth?
the thing is, there are "Super tachs" and then there are "Super tachs." The first ones had separate senders WHICH WERE NOT ELECTRONIC. These used expensive and now impossible to find mecury batteries and a RELAY to activate the meter. Good luck finding a sender that works
The first one I bought in the '70 or '71 was a one piece electronic version
