It's an unusual silver mark STER AND LIKE fk. However as long as they are marked that's the main thing. They are good as magnifiers and I sell many of these ate outdoor shows. Note the filigree handle, lovely and the little knob is how they open. Also, the frames have beautiful detail. There is one tiny scratch a one of the lens about 1/8 of an inch long - please see picture. Chain is about 40 inches long but the first 3 1/2 inches is closed.
