Most popular tach in the 70's and other stuff

Sun Tachs were the hot item to have in the 60s and 70s. Here are two Sun Tachs I own, both are dated from the late 1960s. One is a ST-602, 8,000 rpm and the other one is a ST-603, 6,000 rpm. They are both free standing tachs that do not need a transmitter. Most Sun Tachs in the day needed a transmitter to work. Both are in excellent working order. I removed the ST-603 from my 1965 Pontiac before I sold it. One of them will be going into my Duster in the near future.
