The two piece is no longer being made.
A little history: A friend, my brother Bob, and myself got together one evening at a Montana Bowhunters convention 13 or 14 years ago and convinced Dave to put a Robertson Connection on his one piece longbows and cut them in half. With three pending orders, he decided to give it a try. Cookie got the first two piece, Brother Bob received the second (even though I was the first to place an order), and I have the third. Dave says the three piece is a lot more popular and easier to make, so he doesn't make them any longer. Mine is not for sale, neither is Brother Bob's, don't know about Cookies. I have only seen a few appear on the classifieds in the last ten years.
