My dad inherited a Winchester Model 12 from my great-great uncle that he had used a trap gun, and I'd like some info on it if possible. Barrel is marked
Winchester --MODEL-12-12GA-2 3/4 CHAM.--
Trademark -------WINCHESTER PROOF STEEL-----
MADE IN USA FULL
serial number is 17955**
It has a vented rib, 26" barrel with 2 beads. I'd consider it to be in 90% condition. Any info would be appreciated. Thanks!
