how old is a national firearms 12 gauge shotgun serial number A23163
Can't be before 1892 or after 1931. If it is hammerless AND has fluid steel barrels, it is after 1903. Open hammers and/or damascus barrelled guns continued to be manufactured after that date also.
The current Barrett Firearms does not make a double shotgun. Exactly how is your gun marked?
Utica Firearms Company: Trade name used by the Simmons Hardware Company of St. Louis, Missouri on firearms they retailed c. 1900. Yours is a bit unusual if it has damascus barrels but no exterior hammers. Shooters want fluid steel barrels, decorators want side hammers, and few collectors want hardware-store guns, so I'd say unusual is not a good thing. Even in NRA Excellent condition (98%+ original finish) I doubt if you could get over $200.
