To Banjoman,
Perhaps your are aware of this publication; if not, it is the best overview of early TN gunmaking I've seen, with 1820 thru 1860 census and manufacturing census breakdowns of gunsmiths reported by county, and by output, broken into Eastern, Central, and Western Tennessee regions. It lists gunsmiths in Campbell Co. and Fentress Co., the area we discussed earlier with regard to the posted rifle. If you have not seen this TN State report, google "A Preliminary Survey of Historic Period Gunmaking in Tennessee" published in 1991 by the TN Dept. of Conservation's Archaeology Division. The entire paper is posted so you can read it, including all data sheets on census listings with references to counties. I think you can print it off, maybe 35 pages or so. Shelby Gallien
