Im no expert with wood, but I was confused too. It looks like that blank would have been very straight in the grip with some nice figure in the posterior butt. But, like you, Im having trouble putting that stock together with that blank. With that much figure in the stock, and if that blank was used, I dont see any way possible the grip could be straight. Again though, and other than having several stocks made, Im no expert.
