Guns like this were sourced to be shipped to the colonies in great numbers and were generally referred to as "trade guns ". Richards being in Liverpool a large port would have been involved in this trade , guns for export to African ,India as well as supplied to ships etc. would have borne no resemblance to the guns made for the home market .Birmingham makers were also involved in this and some of the guns produced including percussion guns that were made well into the 20th century were hardly fit to prop open a barn door .
