I have a Browning 16ga that I am guessing is an older A5. When I was a young man my parents told me that it was a "sweet sixteen". From the research I have done I disagree but would like to know someting about it. Been to the Browning site didn't help. The SN in front of the loading chamber is X188__. Can anyone tell me what year range this 16 is? The # on the barrell and the forearm match the reciever. Only other markings say 2 3/4 inch, made in belgium, brownings arms company st louis mo. It also has the safety that is in front of the trigger that sildes forward and back.
