Nit Wit, you peaked my interest on this gun. I pulled up a copy of this book on the internet and checked out the image on the cover. I wish that it showed more detail. As I primarily collect percussion over under guns, it is very interesting to me. The gun is similar to B. C. WOOD's guns, but the drop of the comb on the buttstock and, from what I can make of the image, the breakoff is not typical of him (or the 5 other makers of these type underhammer guns that I have). If anybody knows the maker of this gun or has better images, I would be extremely interested in seeing them! The author lived in Wellsboro, Pa., but I do not know of any gunmakers in that area who made this type of combination gun. For information, in upstate NY, percussion over under combination guns are often called "Adirondack rifles". I also just ordered a copy of the book as it looks like "a good read".
