I've always admired Duclos' work and have built a few of his designs. On the tribute site http://www.craftsmanshipmuseum.com/Duclos.htm, there are some examples. There is one called the Mystery Engine. Apparently there are no surviving examples or drawings. So I used the two available photos and drew it up on cad. Now its just a matter of building it and see if it will go. I wonder if anyone else has taken a stab at this one.
