Williamsburg Gunsmiths Mostly Repairmen"Because imported firearms were cheaper than those made in Williamsburg - typical of many goods in colonial America - the gunsmith mainly repaired arms and other objects. Gunsmiths often repaired axes and other items made by blacksmiths, cast shoe buckles and other items like bells, and sometimes repaired silver objects.
Rifles were the only Virginia arms produced in quantity. Rifle production was concentrated on the frontier to the west of Williamsburg." - Colonial Williamsburg Official Website
