Ken Breseine is the closest i can come and he lived in Warsaw NY and i met him in his shop in 1987.I made him a German styled percussion lock and a double set trigger and got a nice 38 caiiber bullet barrel with false muzzle for an Eastern target rifle.I got involved with a lot of automobile work and never started the rifle and I think I sold it to a Canadian.Much more money in cars than muzzle loaders.
