In reading about the 1760 Massacre of Long Cane SC I stumbled across this info re Tobler's FT at Beech Island, New Windsor Township across the river from Augusta GA
"John Tobler, a Swiss settler, had set up a thriving plantation there that included an ironworks, a clock making business, and a printing shop that published The South Carolina Almanack. He, like William Calhoun, was engaged in Indian trade. It is likely that the Calhouns and Tobler were already well acquainted. Tolbert's extensive compound was enclosed inside a sturdy palisade fort.

You suppose there might have been a gunmaker??
What other pre revolutionarty war ironworks are known on the SW frontier?
