Thanks!
The wood in the Harton-made grips is Walnut, what variety I'm not sure, from Forum member stevem. If I remember the story correctly, Steve lives or visits the Northern California region where many rifle stockmakers live and collects their offcuts from way high dollar stocks. Steve is responsible for several grips I and others have. Alan has had supplies of it in the past and Jack Huntington guns wear a bunch of it. Search posts by stevem to see more.
