No maker marks, but identical to the Francaise Fenton cake plate. There are some very light surface scratches to the face of the plates, presumably from use. There is a black speck production flaw or paint?
On the pedestal that was unable to be removed with cleaning perhaps it can be scraped away. All else would be production flaws, such a some swirling within the glass and lines near the seams on the pedestal.
