Hey Fellas, The book, Seeing Through the Eyes of Yesteryear, by the late Patrick E. Hallam, might wake you up a bit. I tested Patrick's thesis, and he is/was absolutely right on. I have made 2 sets of 3/5 proprtional dividers - the small one for book photos, the other for gun layout. Once I know TRIGGER REACH & DROP, all the rest of the butt stock is so easily laid out including all inlays, especially the patch box, toe plate, and so on. Yes, you can do it by eyeball, to a pleasing result, which will always reflect 3/5 proprtions, or you can emply proprtional dividers to educate your eyeballs. REgards, Peter A.
