I would like to recommend an excellent book on a mans work in the building and involvement of some of the finest flintlocks made. The book is a biographical history of Keith Casteel of W. Va. The book is printed on fine paper, hard cover and in color, covering his start and progression of these fine arms. Gold inlay, silver mounted and silver inlay, Scenes both carved and chiseled in relief. Just a exquisite book. The book has about 10 rifles featured, with a story behind each one. It is well thought, and well written. The cost is around $35. I am sure if anyone purchased it, they would treasure it.
