This single-shot needle fire pistol is marked v. Dreyse Sommerda on top of the breech, and the serial number 4807 sits just below the cocking piece. It has a 7 3/4-inch octagon-to-round barrel with a .51 caliber rifled bore and a cannon muzzle, and it measures about 15 inches overall. The barrel swings to the side on a bottom operating lever for loading, and the pistol cocks on opening.

This pistol suits a collector of needle fire arms, especially the Dreyse series, rather than a buyer who needs a modern handgun. The listing says about 97 percent of the blue remains on the barrel and action, with some spotting on the left flat near the rear sight, and that the spur trigger guard and operating lever have turned gray. The action functions correctly. Because it is a handgun, the buyer must be 21 or older and must receive it through a licensed dealer.
