I brought this Browning auto 5 with serial number FN 134504. Trying to find out as much information as I can on it. What year was it made, where it was made, and what it maybe worth today? It is in really good condition.
Since the serial number starts with FN, are you sure it's a Browning? Check the left side. What's it say? FN made the Auto-5 for Browning, but only the guns shipped to North America were marked Browning. The rest of the world had FN 1903 Browning Patent Self-Loading shotguns. Same thing, but if it's marked FN, it's not a Browning technically. A lot of FNs have come home with servicemen stationed overseas in the 75 years since the end of WW2.
