Good. The metal surfaces exhibit a smooth dark patina with light-moderate pin prick pitting overall. The cylinder engraving is partially worn smooth. The revarnished grips are about good with traces of varnish. There are two large chips on the bottom edge of the right grip. The butt has a series of moderate nicks and pressure dents with a carved "X". From the Will Hoffeld collection, purchased from John Fox at the Las Vegas Show in October 1995.
