pair vintage white milk glass torchiere reflector, light diffuser lamp shades

Matching pair of vintage translucent white glass reflector shades, 6" in diameter across the rim, 5" in height, 2 1/4" at the fitter. These are not marked that I could see, though are probably Rembrandt or Stiffel lamp shades? These are both in very good condition, some slight roughness to the rims, but no chips or cracks.
