Well,
This machine HAS made it to the west. To my workshop on the Riviera.
But sadly without the user manual. I still haven't figured out how to make a working DPV out of the bunch of parts you can see on the picture. The batteries are quite mysterious. I don't know what to fill them with, their voltage, how to set them in the shell, connect them to the motor...

This is definitely a challenging puzzle, but I'm confident!
If anybody has a clue???
