Great idea! I was wondering this kind of thing myself recently. However, like too many historical objects, shaving paraphanelia would be obscenely hard to track. I presume that most of our items have little, if any, provenance to speak of. If anyone can track their items, I can't wait to hear about it!
Great thread! All my stuff is new so no chance for me, but I'd love to know if any famous people through history have passed down their bits and pieces.
