Winchester model 42 .410ga pump-action shotgun, choked modified with a donut post vent rib and marked as a pigeon-grade gun, Don Combs said this gun was factory engraved, Were not selling it as such as that being the truth because of no factory records and, so many fakes out there. Features double diamond wood that appears to have been varnished to us. Regardless, this is a beautiful gun at a great price. This is a grade 5 Winchester pattern.
