This is Truly a one-of-a-kind percussion pistol, made for a very specific customer. Unlike most double barrel pistols, wich have a trigger for each barrel, this one has off-set hammers and a single split mainspring with one trigger pull expelling both barrels. The ramrod is also set on a swivel allowing it to be used for each barrel without detaching from the pistol. Although it has a wonderful aged patina, the frame and barrel is made from brass. Bottom of the barrel is stamped with the English crossed halberds. Beautiful Birdhead grips are intact and without cracks or dings. Truly a must have for any gun collector!
