I won't give his name but you guys won't accidently find him. I have known him for many years and blackpowder is far from his thing.
He IS a professionaly trained gunsmith -- he even served an apprenticeship of sorts. He seems to have become odd as he has aged though. Beligerant, like the proverbial "old man," and hyperactive. I will say this though...
At the same time he was not making me happy (to the point where I wouldn't let him apply the finishes to my own kit gun (after we Aqua Fortised it), paid him too-much in full, and took it back) he had finished making from scratch someone's rare wood forearm and rear stock, including hand-made screws and checkering and patterns and it was so nice, so perfect, so fine and beautiful I suggested he enter it in a show somewhere. 'course it was $2,500 and that did NOT include the materials...
