What is the age and value of an Auto-5 Gold Trigger serial 73G25741 with a full choke Belgian barrel in very good condition?
For age, check the browning.com site; yours is a 1973 gun, and the G tells you if it's a standard or 'Light' model (i forgot which is the G and which is the M...). Good luck.
What is the value of a 1969 Sweet Sixteen with a plain barrel gold trigger and a safety in the trigger guard in very good shape?
The safety has always been in the trigger guard of the A5. Early guns had a front-to-rear safety in the front of the trigger guard. Yours should have the later style crossbolt safety behind the trigger. Plain barrel Sweet Sixteens in excellent condition will bring $1000. They drop off fast as they get toward 80% condition. In 'VG' condition, $650.
