You are bidding on a ships lantern manufactured by National Metal Stamping & Spinning Co. of New York.This is a functioning lamp with some dents and dings, it is missing the globe. It still works well, I have used it when the lights go out, if you raise the shroud before you move it to another room the flame won't blow out. It has a lot of character and needs a home with a collector of maritime antiques, instead of serving time in my garage until the next black out. I do not know anything about these lanterns but I will be glad to answer any questions you may have about the condition of it. Feel free to contact me. Happy bidding!
