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. RR-120-P to Y-403-EP = 99,178 Y-000-WW Excluded |
