Hi,
Of course everyone is focused on early American makers. In Europe, division of labor was the norm for centuries. Gunmakers farmed their work out to specialized engravers, silversmiths, and goldsmiths. Provincial makers might engrave their work but often sent it on to the cities when really high-end decoration was ordered. I am sure that in bigger American cities such as Philadelphia, New York, Boston, and Charlestown some decorative work was farmed, but what choices would a rural gunsmith have?
