An oddity. Single-barreled .41-caliber percussion pistol, with double chamber that contains two powder charges and projectiles that are simultaneously fired by two separate hammers. Hammers are released by a single trigger that allows them to fall in proper sequence. 5.5" octagonal barrel contoured into a radical stepped-down shape and spur trigger. Frame is brass, with scroll engraving. Barrel blued and marked "Lindsay's Young America". Estimated to be fewer than 100 manufactured between 1860 and 1862.
