This is a compact percussion pocket pistol featuring an over/under barrel configuration and a single trigger mechanism. The pistol is designed for concealed carry and personal defense, typical of mid-19th century craftsmanship.

The barrels are arranged vertically (over/under), and both are fired via a single trigger, alternating or sequentially depending on the mechanism. The action is percussion cap-fired, common in the pre-cartridge era.

The grip is made of finely shaped ebony wood, offering a sleek and elegant appearance as well as a firm hold. The frame and barrels are typically constructed from steel or brass, sometimes engraved or proof-marked, depending on the maker and origin.

Due to its size and configuration, this type of pistol was popular among gentlemen and travelers for its discreetness and ease of use.
