This listing is for a vintage Art Deco B&H oil lamp holder wall mount sconce with the swing arm bracket.  The bracket is dated 1880... the holder is dated 1881.  The holder measures 12" long.  The bottom of the bowl measures 3 1/2"... halfway up measures 4 1/4" across... and the inside top measures 5 1/8" across.  It measures 6 1/2" across the entire top of the bowl.  The post measures 2" long. The bracket measures 4 1/2" long.   There are scuffs and scratches on this from over the many years.  Some of the shiny finish is off.  There is a place at the top for a reflector.  This is a nice piece from a nice estate.   Thanks for looking!
