Fine, retains 70% of the period refurbished blue finish with some scattered small patches thinned to a smooth grey or brown patina, some scattered light handling marks, and well-defined engraving. The refinished wood is very good with a few scattered minor dings and scratches, a hairline crack in the left of the forearm, and crisp recut checkering. Mechanically excellent.
