Dave, you are quite correct. One can read and see pictures a long time and gain a lot of knowledge, but, when your hands actually hold the original you "see" things that the pictures would never show. When we are blessed enough to actually have a mentor that allows hands-on, it really makes a difference. My mentor used to tell me "you guys look a lot but you don't see"; and he was very insightful in that respect. But when I picked up his originals my hands and fingers "saw" a lot that I would never have seen in pictures. I am currently reading Cooper's book, The Kentucky Rifle and Me, and am amazed at what she and her husband were able to buy and handle in the 30's thru 50's. Talk about loaded with information!
