Italy weeping willow Lamp I know nothing about...help

I received this interesting lamp from my mother. She said that she found it in a old abandoned antique store and she knows nothing about it. It looks like a weeping willow tree all the way around it. It still works and it looks hand made. The only markings on it are the ones in the picture. I tried to upload a pic of the top of the lamp as well, but I am not sure if it worked. The top of the lamp is sort of curved (not perfectly round), which further assures me that it is handmade. It also has a very fat plug on the end of the cord.I took it to an Antique shop here close to home and the guy really wanted it, but wouldn't give me a price or tell me anything about it. I asked him what he believed the age to be and he wouldn't tell me an estimate on that either. So, I am sorry I do not have anymore information, I was hoping someone here would know a little about this sort of thing. Thank you.
