When was your U.S. model U built.

     To determine when your model U was manufactured, determine the the car's serial number from the medallion on the instrument panel.  Convert the letters into a numeric using the FEDCO chart above.

Then Check the number against the chart to the right to determine the approximate month your car was manufactured.

I developed this chart based on the total Detroit production for 1929 divided by 12 months.  Remember this is only an approximation.
