I am looking for some information on agun thaT i have. The gun is a very old fabrique nationale de armes de guerre. It is a 16 gauge with 30 inch barrels that are choked full and full. The gun is a boxlock and have very nice case coloring with a minimal amount of engraving. My grandfather picked up this gun in india probably 35 years ago and the gun is much older than that. I have some pictures if anybody would like me to post and I also have the serial number. If anyone knows where you can trace the serial numbers etc that would be great. Thanks for your time.
