Bergeon Ruby Jaw Balance Poising Tool (poise) in box

Bergeon balance poising tool with Ruby Jaw Jewels Jaws in original box. It's perhaps more than just a bit dusty but everything appears to be excellent condition to me; box is excellent, jaws are excellent, overall tool appears excellent. Marked with the original acquisition date by the first watchmaker to have used it (and, in case you're interested, I acquired it from his son). Images do a satisfactory, but perhaps not fantastic job of representing the item, and offers are always welcome.
