Fine. The barrels retain 60% of the brown Damascus pattern with the balance a mottled gray patina. There is some mild pitting on the barrels. The remaining surfaces retain nearly 30% original case colors in and around the protected areas. The wood is fine showing some minor pressure dents and scratches and a few blemishes in the overall crisp checkering. An incredibly hard to find shotgun of spectacular quality and condition.
