Very fine with 60% of the browned finish remaining with some areas of discoloration and spotting and clear barrel markings. The breech, hammer, locks and other casehardened components retain approximately 30% of their original finish. The trigger guard and butt plate retain 60% of their original blue finish with some areas of discoloration, mostly on the butt plate. The refinished wood is very good with numerous scratches and dings, well defined checkering, and some slight chipping of the edges. The case is very fine with several scratches on the exterior, including one running nearly the entire length of the top, a large crack coming off one of the corners, and some slight tears and staining to the interior. Mechanically excellent.
