Those apear to be a loaned set of gaffs. Being an antique expert I know where they came from. Nicoliae Tesla origionally owned them and loaned them to Alexander Grahm Bell. Or was it Grahm Nash?? Or Neil Young?? Hard to remember back that far. I hope you can show this to your wife and get them appraised as you will need to sell them in your impending divorse if you decide to keep them. Get a good lawyer, ask Tesla about Franklin, hes' up here in heaven and still stewing over that deal. Hope this helps, Later, Watson
