Start with http://www.browning.com/services/dategun/index.asp for the date. While you're there, identify the model. You'll need that, and its condition, to find a value. The Browning website is notoriously incorrect about the manufacture dates before WWII. Post the serial number here like this 108XXX or 66XX. Condition is the driving force on these guns along with the barrel configuration. COMMENT: An observation, is that you claim a 20ga gun with the Ogden address. The Ogden Utah address is only found on the barrel. Browning didn't make a 20ga gun with that address. Please verify the guage, and see if the serial number on the barrel matches under the receiver, then re-ask the question for the age. (remove the forearm & look at the barrel ring that holds it to the magazine tube for the serial# ) I believe the gun should probably be a 12 or 16ga.
This is an Auto-5 Shotgun
Yes, but not easy to find.
Basically impossible to value with just the serial number.
not much more than its US or Japan made counterpart
