That 3 digit code on that position on the data plate is the build date. The first digit is the month and the next 2 digits is the day of manufacture. Mine is 208 which is February 8th and his is B04 which is October 4th. The first digit can only go to 9 so after September they went to letters to signify the month. "A" is September and "B" is October and so forth.
