"17th Century Oil Lamp"
17th century wrought iron oil lamp with a flat "double spout". The reservoir is located behind the wicks, if we can call it a reservoir, and the whole thing pivots on a cylindrical post fixed to a tripod base. The photos speak louder than words! The vertical rod serving as an axis is riveted to the base (no screws, no nuts). This same axis ends with a hook that allows it to be carried/moved and possibly hung. Do not hesitate to ask for more photos if needed.
