Wow!
Those are really beautiful.
I think the Wood may be Cherry...grain structure is definitely not Walnut, anyway.
Cherry would be a very good Wood for these kinds of Stocks, too.
I recently got a 1st edition of Mr. Roper's Book on Hand Gun Shooting.
Good book!
He was deeply into all aspects, and very knowledgeable.
Plus, a smattering images of Hand Guns outfitted with his Stocks, too.
