what i did was use your pattern in conjunction with the gi pattern which i did trace from a flat photo on my monitor (yup) to get my pieces . I do know the original was for a scope and the history of it but i built this for iron sights and it is much different in how it fits. My pattern has the cheek piece higher on the stock , like yours, and is also thinner then the original. I also used your idea of formed leather inside. I used the gi shape but it isn't the same at all it is just looks similar and seems a good idea so the pads can be adjusted for thickness. i also lengthened it so it could use the sling loop to hold the rest in place, the originals were screwed to the butt. In essence it only resembles the GI model. But tracing an outline from a monitor only gives you a picture , no actual dimensions so that was the hard part actually getting the thing the right size and in the right place.
