Fine. The barrel retains 25% original blue finish concentrated on the lower flats with the balance having a smooth mottled brown patina. The cylinder has a smooth brown patina. The frame retains 95% original silver plating which shows aged blistering and is beginning to darken a bit with age. The grips are very good with 80% original varnish remaining and showing a few minor dings and dents. The markings are clear. The action is fine. The case is very good with a repaired broken corner and a worn hole on the lining in the bottom which has faded mostly to brown.
