Functions, no finish remaining, the lettering and engraving heavily worn to the point that I could only tell what some of the barrel markings said because I know what they look like on more intact guns. Has the appearance of having been rusty then polished down. Still has pitting from when it was rusty, especially the barrel. Grips, excellent.
