You can see the latest model of hurdy-gurdy-cello below:

And also below, you can see the very first model (end of the manufacturing):

It is made the same way as the bowed hurdy-gurdy, the pitch is 1 octave below (tuning GDG, with cello strings), but it doesn’t work in the same way, as the crank handle acts via a right-angle so that it could allow a playing close to the cello playing. The soundboard is made of spruce, the body is made of cherry-tree wood, the neck is made of walnut, the tuning pegs are made of ebony, the tailpiece is made of yew tree, the bridge is made of spruce and the fingerboard is made of chequer-tree.
