Ceiling light fixture from my grandmothers house. circa 1930's or 1940's

This light fixture came from my granny's house before we sold it. I've probably had it 25 - 30 years and just now found it. The house was built in the late 30's or early 40's.

It still has all of the original hardware as you can see and I plan to replace all of that. I've seen lot's of vintage shades online, but I haven't found one that has the small matching glass globe like this one does. It's very, very heavy and probably 12+ inches in diameter across the widest part. The shade goes under the light bulb turned up like a bowl.

I really don't know any more about it. I can't find any marks or anything on it. I'm going to hang it in my master closet. :) I can't wait! I've always loved it.

Have any of you seen a light fixture like this? Anyone have any info about it? I would really appreciate knowing about it.
