This isn't exactly the same, but if you put "brown drum shade pendant light fixture" into the Bellacor.com search box, you get all sorts of options. Plus a decent lamp shop could make this for you easily. It looks like a brown silk shade, a glass diffusers and a cord.

Try Moooi. I think it is called the round boon.
