ENGINE NUMBER
While looking for information in the Service Bulletins I found the following. On page 228, February 1928 " The letters "AA" which were formerly stamped on engines intended for Truck use have been discontinued. All engine numbers are now prefixed with the letter " A " only. ??? Thought AA's were stamped AA and number. Any insights ? BIG Fire in Prescott,AZ

Re: ENGINE NUMBER
That was when the A and AA used the same clutch springs. The engines were stamped with
AA when they had the stronger springs than the A.

"A" and "AA" prefixed engine id's
The conversion back to the "AA" engine id prefix was covered in the May 15, 1928 Indianapolis service letters. And, this is covered in the table at http://aafords.com/aa-information/#feidm as well as being covered in the RGJS E Supplement. AA-98977 has been found helps define the end of the "A" prefixed ID's for the AA's.
