TEN TEC SERIAL NUMBER DECODING Example: Serial Number 06A10108 06 at the front is month of manufacture, or scheduled production run month. If we were scheduled to build a run of a particular model in June, and for some reason we were delayed to July or August for that particular run, we'd still put "06" at the front of the serial number. "A" is a separator between the groups of digits. "1" is the production run # for that particular month. "010" is the unit number. "8" is the year of manufacture. A "C" separator began being used in 2000. 1.
