My 2 cents and I've had a number of shotguns stocked by Guild Members is it is indeed the same blank, but not laid out the way they would have laid it out as it would compromise grain flow in the wrist area. Its probably fine to do this in a through-bolt gun, but most wouldn't go that route. Agree that it is Feather Crotch American Walnut, or Claro Walnut. Its not of the thin shelled variety.
