Like the title says that is what I have come in possession of, Colerain barrel in .36. It is a barrel and that's all there is to it, not vent, sight dovetails, nothing but the barrel. I have never built a rifle before but have put some kits together and this looks to be a whole nother animal. Any and all suggestions as to what to do first and how to do it would be more than appreciated. Does someone sell a semi-inletted stock that would let me get started on this project? What size/maker/style lock, flintlock of course, would be appropriate? Should I send it to someone and have them build the rifle? Got a TOW catalog but until I know what to look for first it really isn't much help except it makes me drool over the possibilities. An ignorant mind is what you are dealing with here and ignorant minds need to know. I'm one of these guys that can take about anything apart but the hard part is putting it back together again correctly, so I've got that going for me. Thanks for any and all help with this rifle. I'd rather not screw up the barrel if I can help it. Imalarduss
