The typical pepperbox revolver is a sleek and small .31 caliber double action pocket gun, like the Allen & Thurber standard type. This one, however, is anything but typical. This London-made gun is a far larger than normal, and sports 8 barrels, with a center square of four and an addition four outside of those. Those barrels are .36 caliber, and the firing mechanism is single action only. In addition, it is unusual in requiring manual indexing of the barrel cluster between shots - most pepperboxes index automatically when the trigger is pulled. I have no further information on the date or original of this piece beyond its “London” marking, and bring it to you as just one example of the wide variety of this sort of firearm that exists.
