Larry Clark Black Powder Guns

Anyone know of this maker? He is my Brother, and I know he made/maybe still makes custom hand made guns. He used to make them in the mountains of NC I think , and I believe he lives in NY now. Sadly my family was never a tight nit one, and we all kind of spread across the world. He is the oldest and I was next to the youngest out of 11 total kids between 2 marriages. At any rate, I would very much like to buy one of these for my collection and for something of my family to pass along.
