Love these Lamps

I bought this pair of lamps at a garage sale because I loved the ornate design. I was told they came from a ship, the captains quarters. I really didn't believe them or care. I loved the lamps. There are markings on the bottom but the #'s are not clear. I also couldn't get the other 2 pics to load!! I believe the are made from cast iron. I've looked until I have almost given up and ran across this site. I'm hoping someone can help me or steer me in the right directions. TIA
