Asian Lamp

This is an asian themed lamp that I got at a local consignment shop. There are no markings anywhere on it except on the sockets which read: Leviton patented 250W 250V. It is hand painted porcelain with a carved wooden base. Im not sure of the time period, but based on the cord 1930's maybe? I have taken this to a few local antiques dealers and none of them knew any information about it. I cannot find anything like it on the internet so I am hoping someone will know or be able to find some kind of information about it. ANY information would be greatly appreciated. Where it was made, approximate date it was made, any place I could go to maybe find more information on it would be very helpful. Thanks for looking and for any input.
