Habitat Restore find hanging light -Info?

I found this interesting hanging light at a Habitat for Humanity Restore. I'm interested in when it was made. Scroll work and frame appear to be copper or brass, bodies of lamps some other metal. Finish is rusted. It's approx. 3 feet in length. One of the smaller shades has a fairly good sized chip in the top rim (can't really see in picture), I've looked but can't find a glass shade in this style.
Any information is appreciated. I plan to use it over a kitchen island.
