I may have confused the answer , as Bill said, is it a pre carved stock meaning shaped like a gun? if so, like Bill said some one can help you finish it, or put it together for you, If it is not shaped , along piece of wood with RR and BBL run, call D Keck as JD said. what worries me is the BBL channel , would it effect his pantograph. years ago I had FAJAN do a ML stock from my old stock. They charged for the setup. And it cost a lot more than the pre carves on the market at that time. I have delt with D Keck, his work is VERY good. If you could post a pic let the guys see it, every one will know what direction to go with your "pre carved blank" A little more info, a lots of brains to pick.
