Data Plate

Posted On: February 27, 2015

The first line of a data plate indicates the Model

  • 1934 8 cylinder is 850Y or 850X
  • 1934 6 cylinder is 652Y or 652X
  • 1935 8 cylinder is 851
  • 1935 6 cylinder is 653
  • 1936 8 cylinder is 852

1936 6 cylinder is 654
The second line is the Serial Number which is a numerical code followed by an alphabetical suffix.

The serial is derived from the number stamped on the right hand front frame rail, plus a count of 1000.
Example: if a 1934 car frame number is 1100, the serial will 2100.
Example: if a 1935 or 1936 car has a frame number of 3120, the serial number will be 4120 except if it is supercharged.
If supercharged, the serial number is prefixed with a 3, so frame of 3120 would be serial 34120.

The alphabetical suffix indicates body type:

  • A – Sedan
  • B – Brougham
  • C – Touring
  • E – Speedster
  • F – Cabriolet
  • G – Victoria
  • H – Phaeton Sedan
  • K – 7-Passanger Sedan
  • L – Chassis
  • M – Coupe
