To amplify what Jerry said, Issac Haines was a true master. His work always had perfect, crisp lines, and immaculate carving. His guns are the only originals I have seen that match contemporary longrifles in fit and finish. Even though you are buying a kit with a precarved stock, a lot of wood still needs to come off that stock and as you remove it, you need to maintain the crisp lines. An understanding of architecture and technique is imperative to reproduce a proper Issac Haines. Make sure you study his original guns, photos or in person, and get a good book or two on building longrifles. I suggest you at least have Peter Alexander's book, Gunsmith of Grenville County. I think he does a good job of explaining proper architecture and how to achieve it. The lock panels back is the hardest to get right. That is where a Quaker stock can come in handy. You practice shaping the lock panels and butt stock before you start your carving. This is what they do in most of the carving classes these days.
