I just went there. There are none listed. The good thing about eBay is that if it is worth more, people will bid it up. If you price it too low someone like me will snap it up.
This is a mechanical, non-computerized machine. I heard through the grapevine that they started making them with plastic parts toward the end. But the original ones were made with metal gears. There was also a flood in Switzerland and that ruined a lot of stuff. So it is buyer beware.
Try to list it with date of manufacture.
I would like to bid on it once you get it on there.
