These dates were gleaned primarily from Sauerfan's timeline and the Shirley/Vanderlinden book. The serial number and dates are approximations only.
I decided to share it here since this is where much of my limited knowledge came from. I compiled this quick reference serial number guide for dating 16ga Browning A5s and the Auto 5-3 Shot, by serial number. A common mistake I have seen in many, many, gun shops and online sites is to assign the 12ga serial number date to a 16ga. Browning 12ga numbers began with number 1 in 1903. This guide is for the Browning A5 16 gauge only.
