Just another comment re:
"Smith's weren't longhunters, they were civilization and stability."
true to a certain extent; however I have read early pre-1700 Indian relation documents, of both french and british origin, in which a wide variety, both tribal and geographical, of Indian petitioners and negotiators were requesting/demanding that gun/blacksmiths be permitted or licensed to operate in Indian controlled areas. This would be well in advance of the settled frontier.
Admittedly, from what I have personally seen, most of the work was in repair and maintenance of arms rather than actually building them; but then I'm more familiar with the French colonial economic system than the Anglo-colonial one. The French system VERY strongly dis-encouraged colonial manufacture. I am not aware of ANY colonial gun builders under the French area/regime; though I would be joyful at being found in error.
That is true, but most smiths were generalists in the country and specialists in the towns and cities. Whitesmiths, cutlers, farriers, wheelwrights, anchor and chain forgers, naglers, ironmongers, rolling and slitting mills, charcoal burners, gun and locksmiths were found in town where they had a large enough customer base to make a living. Country smiths needed about 15 to 20 farms to keep them busy all year.
Mr Roy Jordan of Pender County, NC made Oyster knives, flounder gigs, welded springs and harrow tines, shod mules and oxen, made and repaired log chain, sharpened axes and turpentine hacks, resteeled plows,repaired oyster dredges and trace chain, shrunk tires and made barn hardware. That was in the 1940s when he was in his 60s. No telling how hard he worked when he was young and healthy. Coastal NC in the 1940s was a lot like Coastal NC in the 1840s and probably real close to 1740s. The same farms were there with the same families and industries. Corn, peanuts, rice, timber, tar, fishing, salt and gunning. If you new the Skippers you could get some nice wine, the Foys had a tidal mill and a good carpenter. The Nixons had a small forge. Roy had about 15 farms within walking distance to his shop and cars were rare until after WW 2. I think Pender county NC is a good approximation of a country smith and his clients.
Down in Wilmington, on the Cape Fear, Wilmington Iron Works was built in 1840. When I was buying Iron from them in that 1990s they still had a 450 lb anvil. 500 lb swage blocks, a 100lb steam hammer, a pattern room, acorn tables, gear cutters and the machine shop was run off overhead shafting and leather belts. They built machinery for the CS Navy yards and the local forts Anderson and Fisher as well as the Wilmington and Weldon RR. They did the same for the Navy in the next big three wars. They stood in sharp contrast with Mr Jordan's small one man shop. It must have been that way up and down the coast and up the rivers.
