Very good plus. The barrel retains 20% original brown finish, otherwise a mottled brown-gray patina. The brass has an attractive mellow appearance. The lock has slight hints of original case colors, otherwise a mottled gray patina. The stock is fine with minor-moderate dings and scratches. Mechanically fine.
