I have become a serial number Birth Date Collector.
It's a sickness for sure, I try and stay with dates that people will still be alive. I just found a Colt SN# 111197 (11 NOV 1997) Will make for a cool 21st Birthday gift next year as the gun will turn 100 years old in 2018 as per my book on Colt Serial Numbers.
Been looking for my birth date for years I'll find it one day, Maybe.
