Vintage Rare Perkins Marine Lamp & HDWR Co. Perko Oil Lamp / Nautical Lantern. There are 2 cracks on the top cover. They do not affect the lamp structure.
The rest of the lamp looks excellent. I do not know if the metal is brass, copper, aluminum, something else or a combination. I picked this up at an estate sale recently.There is a slight oil residue odor if you get right on top of the lamp with your nose. I took the lamp apart to show all aspects. The base unscrews from the top to add oil and light.
