Custom muzzle loader builder?

Does anyone know of a Dave or Dane Miller who builds custom muzzle loaders? I purchased 2 of his guns at a estate sale and would like to talk to him about him making me one if possible. His work is great but maybe not as good as local Cecil Brooks but close. This man maybe from the Ohio,Penn,West Virginia area but not sure or maybe passed away. Can't find anyone who has ever heard of him in this area, if anyone can help me please do. Thanks Larry mcvey1@bright.net
