Colt's No. 1 Derringer was manufactured from 1870 to 1890 after the purchase of the National Arms Company which had previously manufactured this model. It was first manufactured by Moore's Patent Firearms Co. in the first half of the 1860s. Colt called it their "No. 1 National Derringer." It has a rounded nickel-silver blade front sight, the two-line address and "No. 1" on top of the barrel, matching serial numbers on the barrel and butt, factory floral scroll engraving on the frame, "41 CAL" marked on the right side of the frame, and standard thumb print knurled panels for better grip. Includes consignor research related to the development history of the No. 1 Derringer.

Excellent, retaining 97% plus original nickel finish with some pin point speckling of plating visible left side of barrel and minor handling marks on the balance. The engraving and knurled panels are crisp. Mechanically excellent. A high condition Colt No. 1 that will be a welcome addition to your Colt handgun or derringer collection.
