When I worked for Robinson's Firearms Ltd., between '79 - '82, I stocked about 250 rifles, mostly Hawkens, in Claro. It came from either California, Oregon, or Washington, and was all nice walnut. For the most part, the grain structure was harder, tightly pored and very colourful, compared to Black Walnut. It required filling or course, but made up into very pretty rifles. Bastone is a hybrid walnut and is usually harder and heavier than Claro, but the king is English ---GOOD ENGLISH!!
