These are a unique, large pair of genuine antique light fixtures. They are made of a grey cast metal with gold and white paint.
Both are electric but the original wiring needs to be replaced. The wall mounted pieces measure about 16" tall by 10.5" wide. From the wall to the end of the arms is about 13.
Each hanging part is about 9" wide and 13" tall. One has a damaged arm (pictured) and is missing a cover on the bottom (pictured).
