I don't know who supplies the actual wood, but H&R makes all of their own wood stocks except the thumbhole lams in their new wood plant in Ilion, most of their stocks were made in Gardner before they moved, they even did their own hand checkering then, pallet wood stocks aren't walnut, they're a less expensive hardwood, beech or birch, commonly referred to as "pallet wood" here. Boyd's makes the thumbhole lams.
