These derringers were introduced in 1870, produced until 1912, and totaled around 48,000 manufactured. The top of the barrel has a rounded blade front sight and "COLT" in large italic letters and the bottom of the barrel has small British proofs. This early 20th century example has the desirable "illegal"/"unauthorized" Colt Pall Mall address on the left side of the frame along with the circled Vonn Oppen retailer marking. The caliber marking is on the right of the frame. It has standard features and is fitted with a pair of smooth rosewood grips. Includes an oak presentation case with Colt London Agency label inside the lid, key, and .41 RF cartridges. Provenance: The George S. Lewis Jr. Collection

Fine, retains 50% of the original blue finish with the balance thinned to a smooth grey patina and 90% plus of the toned silver finish, showing an attractively aged patina. The grips are also fine with some scattered light handling marks. Mechanically excellent. The case is very good with some light handling/storage wear.
