Tiffany Style Banker Lamp; Dale Tiffany exact Floral Base dark wood

Tiffany Style Banker Lamp I have seen them called Librarian lamps; it has a dark wood floral base that is an exact match to exact style as Dale Tiffany's work I got it at Lebanon Ohio's Paddler's mall for a steel, it is a combination of two flowers on the back side it is basically green stems. I can't find a picture of it anywhere, I have read that each Tiffany peace is different from the next, although this base is an exact duplicate from a few that have flowers and butterflies or dragonflies on them too. I have searched Ebay, Tiffany's everywhere online and I do get a match to the base I believe it was from Dale Tiffany but I am not a seasoned antique collector. I think from the price of others that are similar it gos for anywhere from $100 - 300 but if it is one and only it could be worth far more. Their is green felt on the bottom of it which I do not want to remove, but I do not know without taking it to an antique shop if it is from Tiffany or a knock off.
