With out looking it up, I would guess Highland Park, Mi......OK I looked it up and auto production was moved out of Highland part after the Model T production in the 1920's.

Reason: More info
Well, the code for Highland Park was HM... who knows why?
That's your Patent Data Plate. Mine does not have a space for the assembly plant, just for the serial number???
Was the Patent Data Plate different before 51?
You, they must have changed them sometime in late 1950, Edith was built in Sept of 50 and does not have the space, but here is one from a '50 from earlier in the year
and one from a '51, notice that it has 2 additional patent numbers on it.
