I've never seen one of these before.

Very interesting device Don, thanks for sharing this. As I see it is now sold, did you get it? If so, I'd love to see some notes about how it works, etc. once you've explored it.

No, I saw it on "completed" listings. Somebody else got it. But I don't think I would have paid that much ($50).
