Guys on this site tell me that Royland Southgate made 1008 rifles.
As far as the Old Guys go, do remember that Henry Deringer was no slouch
This flint conversion, likely for the Indian trade, I picked up from the late Cecil Keyser at the OGCA show. Believe Mr. D. man made a few pistols as well.
Dillin (remember him?) says that John Whitesides, Abington, Virginia took about a week to make a plain rifle. He forged & rifled the barrels in his own shop.
Might I remind some of those who still have hair, if you wish to know something about the American long rifle, do begin by reading Captain John G.W. Dillin. His book,
The Kentucky Rifle, is the foundation.
