Such a charming conical, copper light fixture!  Your Arts & Crafts bungalow or your hobbit house will be most appreciative, as will your guests for your having elegantly lit up their way.  

All-original, with hammering on the two "vents" on the side of the cone and on the canopy as well. There's a frosted glass tube inside the lower part of the fixture.

Rewired and fitted with a standard-sized American socket.  You can use any size bulb you want.  

A few links of chain can be added if you need this to hang a little lower.  As you see it, it hangs down a total of about 17 1/4 inches.  It's about 5 1/4 across at the widest point.  No condition issues!
