I am assuming we are talking about a browning auto-5 shotgun.These first appeared in 20ga.in 1958.There should be a number and letter prefix to your shotgun.A example would be 8z,9z,or a 68z,69z etc. If you would include this with your serial number I could give you a exact year of production.
Who made it? Bolt or semiauto? What do you want to know?
