This is a vintage 1960s brass crystal chandelier.  It has 9 arms for the lights.  We have 9 crystal teardrops on it.  There are an additional 42 holes where you could add that many more crystals - we personally like it more sparse.  Look at the design details in the brass - it is quite a nice high quality chandelier.  It measures 23" wide, 21" long, with the chain to cap being an additional 18".  E-mail with questions.
