So LC is you?
If it’s your initials, maybe they were meant to be gifts for the suppliers.
I’ve checked the bottom of Le Creuset, it looks like this.
I checked Staub as well, the stamp is also round, complete different from your huge “Made in France”
I own several Staub pots, the matt black cast iron pots has that classic blue bottom, like your pan. I’ve a wok that has handles like yours. But Staub always includes its name on the handle or made in France on the bottom side of the handle.
But since it might be a sample, maybe things aren’t standardized.
