Colt's Second Model Derringer was based on the design first manufactured by Moore Patent Firearms Co. and then the National Arms Co. before it was purchased by Colt in 1870. They were manufactured until 1890. Colt advertised this model as the "No. 2 National Deringer." This example has flourishes of scroll engraving on the sides of the frame and behind the hammer and a small burst pattern at the breech. The markings and other features are standard.

Excellent overall with 90% plus original nickel plating, flaking at the muzzle, a small patch of pitting on the left side above the extractor, significant original case colors and some light spotting on the hammer, and small marks and scratches. The excellent grips have crisp checkering, mild edge wear, and minor handling and storage type marks. Mechanically excellent.
