These derringers were introduced in 1870 and totaled around 48,000 produced. The top of the barrel has a rounded blade front sight and "COLT" in small block letters. The hammer is the early production "high" variant, and it has the raised bolster on the forward bottom portion of the "bulbous" frame. The early four-digit serial number is stamped on the left of the grip frame under the grip, on the bottom of the barrel, and in ink inside each grip panel.

Very good, retains strong traces of the original blue and silver finishes in sheltered areas with the balance having thinned to either a smooth grey patina or attractively aged brass and a few scattered very small patches of light surface pitting. The grips are also very good with some mild high spot wear and some scattered light handling marks throughout. Mechanically excellent.
