Mike, I agree with you that such a "Piece of Paper" could take the place of all of these expensive and ridiculously complicated gauges. I have never seen one offered commercially, but someone should make and sell one. Your idea works as well as anything else and you could carry it to a gun show or auction with little hassle. To add to my comments, none of these British charts take into account the height or dimension of the shooter's cheekbone and its location in relation to the eye, the most important part of fitting a shotgun. Of course, the Brits want us to shoot while standing on one foot, so what would we expect? The Brits are great shooters, but probably pay no attention to their gunfitters.
