Re: what is this pepperbox?
One source shows an R.S. Clarke in London 1840-1843 and an R Clarke in Birmingham after 1835. One of them might be the maker, or the name could be that of a retailer rather than a maker. Percussion pepperboxes generally date from c. 1835 when the percussion cap came into common use to c. 1860 when the obvious advantages of the revolver made the pepperbox obsolete. Some were made later, but they were defnitiely old-fashioned by the early 1860's.
