Large Vintage Anchor Brass Maritime Oil Lamp Lantern Nautical Ship

Description

This very impressive part of history was originally part of a pair that came off some ship (unsure which) and ordained a fireplace in a mansion over looking Lake Michigan. So it probably came off a ship that traversed the Great lakes. I am unsure weather it was ever used or not but seeing that it was used as décor they could of had it cleaned very well. It does have a plaque that reads "JJ511" I did try to look this up to see if it is tied to any vessels or even naval vessels but nothing has come up. I have found Ships captained by  J.J (initials) and numbered 511 but I'm not sure. Please see the pictures if you have any question please let me know!
