We only have four of these sconces. We believe they are French due to the old sockets we removed and probably from the 1950's or so. The shell motif is so nice for that decorative effect.
Electrical: These sconces have been totally re-wired, to American UL standards in our UL shop. Normal bakelite sockets for everyday medium base bulbs were installed. The sconce mounts with one normal sconce mounting all-thread to a normal electrical box from within the case. All mounting hardware will be supplied.
Measurements: 8 1/2" tall. The shade has a maximum diameter of 8". Projects into a room from the wall 4 1/2".
PER Pair....$485.00 plus careful shipping. At the time of posting, we had four matching sconces (2 pair) but un-known at this time.
