I picked this up a while ago at a thrift shop. I think it is trench art that was done after the war. Its simplicity appealed to me, so I bought it. The lamp is solidly made and weighs about 15lbs. The electrical components look to be 1940's, but it’s only a guess. Is the artillery shell rea? If so, can anyone ID it? I also have a 12 " ribbed frosted glass dome shade that looks like a parachute and looks great on the lamp. Thanks for your time….
