Only several hundred of these rare pistols were manufactured by the Union Knife Co. in Naugatuck, Connecticut, in the early 1860s based on John P. Lindsay's patent. He was inspired to produce a multi-shot weapon after losing his brother to an Indian attack while he was armed with a conventional single shot musket. He was able to kill one of his two assailants, but the second Indian killed and scalped him. This example has the standard barrel markings and engraving, added "172'" on the right side of the barrel, custom engraved dog on the right and deer on the left of the frame, and smooth grips.
