Copper and Brass Nautical Ship’s Lamp. Very nice quality lantern. Copper, glass and brass. I do not know the provenance of this piece. There’s definite patina on the copper as evidenced by the green “corrosion” on all the seams (see photos). Thick glass. 6 1/2” high 3 7/8” diameter I’m not sure how it operates as there is only a 1/4” diameter hole at the top which leads down into the glass globe of the lantern.
