The crank turns and the two number wheels on the left turn, but I'm not sure how to use it, so I can't say how well it's working. The number dials at the top don't seem to move, and the carriage mechanism moves, but not the way I think it's supposed to. But it's a beautiful example of a precision-made machine.
