win 12 pigeon grade guns
If you really have an original Winchester Model 12, 16 gauge, in Pigeon Grade it will be worth $3,000 to $6,000 depending on condition and choke. It should have a solid rib, the winchester proof mark on the left side of the barrel near the receiver, and the pigeon logo stamped on the underside of the barrel, deluxe wood, handcut checkering, etc. There are a lot of counterfeit copies out there. Any good machinist can make the "wp" and "pigeon" stamps, roll them on a standard barrel, and reblue the entire gun.
It's even worse with 20 gauge Model 12 field grade guns that have been "upgraded" to 28 gauge versions which quadruple the price.
Lots of unscrupulous sellers out there and these somewhat rare Model 12s are in high demand with collectors.
