I received a Winchester Model 12 12 gauge shotgun from a family member recently. The shotgun originally belonged to my grandfather. I checked the serial number and it was manufactured in 1929. The shotgun has a 28" nickel steel barrel, the bluing is in good condition, the barrel shows signs of oxidation, it has a permanent modified choke. I'm not really interested in selling this shotgun at this time due to it's value as a family heirloom but I was curious if there was anyone here who might have some idea of what it is worth. If you need more information to accurately determine what precise model this shotgun is please let me know, thanks.
