Unfortunately, there are only a small number of dates in the serial number lists,
and there may be some inconsistencies/errors on the dates that are included.
So, you will have to do some interpolation and may only get a rough estimate for the date of your machine.
You may be able to refine the estimated date by searching the literature and contemporary advertising;
they may tell you when models/features were introduced/discontinued.
Dick Bueschel was especially good at including dates in his narratives.
(I think Mills meant to say COPS instead of COCA).
