Here is an original Tom Kuhn RD-1 yo-yo from 2003. It has only been opened to take pictures. This is the first version which didn't come with the rim weights: they had to be ordered separately. Notice the order form for the performance kit.
What you see is exactly the way it was sold, with the long tube.
Notice the wood imperfection near Tom Kuhn's name. You can see it when the yo-yo has been taken apart too. That's just the part of buying a wooden toy.
We bought two of these back in 2003, and one remains in our collection.
