87 years old.If you have a 12 gauge shotgun then it was made in 1906,if your shotgun is a 16 gauge,then it was made in the year 1919.
If your browning auto-5 is in excellent condition(85-90%)original finish?I would assign a value of 550-650 dollars.
Please identify the model. Looks like it could be an Auto5 made in 1948.
