Please help identify the maker of these lamp

Hello,

I received these lamps from a family who was moving to a different state. I was told they were made by Currey & Co. After reaching out to the company, they were sure this pair weren't theirs.

They're made with cast iron, the center has Fleur De Lis design. The base is measured 9"x4.75". They stand about 38" tall. Each weights about 7 pounds.

There are no label anywhere from the maker.

I'd really appreciate anyone who can let me know the maker of them. Thank you!
