Mystery Machine...Solved

Now I know, what that Mystery Machine is! Did some google search. It is motor for bone cutter! Butchers etc. use it. Never thought that it would be something this cool! Have to try, if it works and do something from it. At least it have great looking knob! Case of the motor is great too. Or actually. It is cool, even it does not work!

In stand, it looks like this. This is newer model.
