This is a beautiful faithful reproduction of a piece of British naval history. A white light hung near the bow when at anchor was a standard way to signal that the ship was not moving - at anchor. 11" tall with a base 5-1/4" 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 1/2" wide. The solid Copper Filling Funnel is an excellent addition, and helps when adding fuel on all oil lamps. Fuel is easily available locally. Lamp oil is recommended, but kerosene works too. Very handsome.
