I just now measured the one piece rifle stocks on quite a number of rifles in my collection at anywhere from 30" to just over 34". The major length piece on original Mauser full stocked military rifles is 33". I have some 90+ blanks stacked and drying, and measured those at from 34" to 42". The 42" blanks are a good bit longer than needed. It's no trick at all to cut 3 foot blanks from mature walnut trees. I simply do not understand why we would think that American stock makers could not quite easily cut 3 foot or longer blanks from our own walnut trees. I must agree with Brent D in this regard. As he says, even 5 foot blanks could be had from native stock. Shorter blanks for bolt sporting rifles were and still are just not a problem from American trees.
