I hope this is the right place to post this but I recently found some books in an antique store that were by Carl P. Russell. Both were hard back books in their original dust covers. One was " Guns on the Early Frontier" and the second was " Firearms,Traps and tools of the Mountain Men". The latter was a first editon and in very good shape but was pretty pricey. Does anyone know of these books? Do they know if they are factual or way of base from true History? I might be interested in them if they are good factual books. Any information would be greatly appreciated. Thank ye kindly in advance!
