Handel Hanging Lampshade

Hello Everyone,

This is my friend's lampshade that he has had tucked away in a box for years. All of the radiating bars have a "HANDEL" imprint like in the 2nd picture. Just wondering when this lampshade could have been made. It has two light sockets that look to be made of brass. The rest seems to be bronze? It is an absolutely beautiful shade with wonderful colors on the front and back. It certainly deserves to be taken out of the box and appreciated.
