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 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.
