"F" prefix with a serial number lower than F498821 = 1989 thru Nov. 1st, 1995
"F" prefix with a serial number higher than F498821 = Nov. 1st, 1995 through the end of 2002
"G" prefix started in 2003 with the introduction of the AccuTrigger
"H" prefix started in January of 2010

Serial number prefix is "C", how is any of the above relevant?
Actually this isn't 100% accurate. I just picked up a pre-accutrigger flat receiver 111FCXPS with a G serial number so there must have been an overlap when the G series started.
