I'm not sure if I still have my handouts from TSJC on stocking a mauser from a blank or not, I will see if I can find them for you in the next couple of days. We used bridgeport mills in school and while they do not have the speed my duplicator has it did work fine. To build a good quality stock from a blank takes time, especially if you are learning as you go. The great thing about Westbrook's book is his attention to proper stock geometry and shaping which carries over to double guns and good layout in general. This is the first gun I stocked and the only gun I have done from a blank, my gunsmithing project pictured here with a small Chamois taken on a DIY hunt in New Zealand.
