yet to be identified

This lamp was from my childhood home in northeast Ohio. The house was built in 1906 and I'm guessing the lamp was installed at that time. It hung above our dining room table and I had heard it was both gas and electrically lit although I can't remember any gas lines ever going to it. It was always referred to as being a Tiffany but I have found out it is not. Still a beautiful piece of workmanship just the same. Someday I would really like to know who made it and possibly its value, until then it remains a mystery
