Guys,
Fun find for this car nerd! Check out the calibration temps on the edge of the gauge. I never knew this was here.

Just when you thought you had absolute values. Let me show you my 73 gauge. The values are different.

Strange, maybe the temp sending unit changed over the years? The assumed part number on the face is different as well.
 
Well, the alternate theory is that nothing can be calibrated in the circuit so somebody just wrote what they measured at manufacturing time...
