Meaning of letter codes at the end of the car's serial number

[Mark L]

What is the meaning of the letter code at the end of the car's serial number?  I recently saw a post that talked about a car with the letter "B" at the end of the serial number having been sold new in California.

What were all of the letter codes, and what did they represent?  Thanks.

Some states...CA in particular...specified a minimum number of characters in a serial number which led Studebaker (or Studebaker dealers) to add a letter to comply with the law.  I don't know whether the factory specified the letter or was left to the dealer.

Thanks for sharing a copy of the letter.
