A buddy bought a 12-gauge DH-Grade Parker Bros. with straight grip and skeleton butt in 1967 fitted with a set of Italian proofed steel barrels. The gun is serial number 88224, and S.F. Cal Apr. 8, 1899, was scratched in one barrel channel on the forearm. We've been on the lookout for the original barrels for said gun ever since. Anyone with a Parker serialization book that can tell me how it started life?
