Dang think I might even have the Bowtie in my closet That GB alluded to
I must because I found these tachometers in my shop somewhere.
The one on the left was a actual solder it up kit or finished by Ace which is long gone now. Worked pretty darn good to but difficult to read the analog meter at the field though in real conditions.
The one on the left was a true kit but the one on the right could be considers a RTF cause ya just pulled it out of the box and held the handle on the cylinder head. The right calibrated wire would just sit there shaking its finger at you
I really agree with CG though unless you are real hard core 'solder em up' kind a guy, it usually makes more since for most just to get a modern inexpensive one.

John, I have a vibrating wire type tac. It was called a Vibra-Tach and uses a single wire with a collar thatslides on the handle to determine RPM.
Actually it is pretty accurate but does not go to as high an RPM as the electronic ones.
