Every now and then I cruise the 'broker to see what's up. I keep an occasional eye on Colt Navy sixguns and the one below came up today. Dovetailed front sight, barrel mounted rear sight. Unfortunately, it was "rode hard and put up wet" and has more pock marks per square inch than a golf ball. Still, it's an interesting look at a custom sixgun from years ago.
