Henry Nock was a highly respected and very talented British gunsmith, who manufactured a wide variety of arms including military muskets for the British Army. He is probably best known on the internet for his 7-barreled volley gun (which fires all seven charges simultaneously), intended for naval ship boarding operations. This particular gun resembled that volley gun design, but is actually a self-priming flintlock pepperbox. Its cluster of 6 barrels is manually rotated, allowing the used to fire six separate shots before needing to reload. The priming mechanism and lock bear a remarkable similarity to the Collier repeating flintlocks, and it is suspected that this system was developed by Artemis Wheeler of the United States.
