UNUSUAL OPEN SALT PAIR WITH MAN'S FACE?

Not sure when I got these, it has been a few years, but they were both black as the night, I do remember that. I didn't know if they were silverplated or sterling, but thought the lines were interesting on them. Obviously, from the photos, not all of the tarnish has been able to be removed. I refuse to use Tarnix, so will just have to retry the polishes again. Anyway, I cannot find out where they are from or who they were made by. They resemble another pair I saw on E-bay, as far as the glass shell inserts, the gold wash interior, the ornate design on the salts, those were French, but I cannot locate any French hallmark similar to what I see on this pair. The hallmarks or maker marks appear on one to look like a clover, 800 and LCC. On the other, the clover is less distinct, the 800 is fine, and the LCC looks more like a CC, so I'm very confused. The glass inserts are in excellent condition, there are some bubbles in the glass, perhaps hand blown? There is a star on the bottom of the glass insert also, which I found interesting. I hope the photos are adequate. Any information as to origin of these would be most helpful, many thanks.
