This large and exceptionally beautiful oil lamp is 11" tall, with a base 5-1/2" in diameter and a large closed hook at the top. The glass is a Fresnel type of design, which is used to distribute the light widely. The wick is 3/4" wide. A faithful reproduction of a piece of British naval history: historically, a white light hung near the bow when at anchor was a standard way to signal that the ship was not moving.
Lamp oil (available locally) is recommended, but kerosene works too.
