pair of vintage white glass diffuser shades, lamp shade reflector waffle milk glass

Pair of vintage milk glass reflector shades for Rembrandt or Stiffel type lamps. These are almost identical, size is 1/8" different at the fitters, I think this was within specs as these came off a pair of matching lamps! Neither is marked as far as I could see.

Measurements are 5 3/4" deep, 7 7/8" across the open rims, fitters are 2 1/8" and 2 1/4". Fitter rims have some roughness, please see photos.

It's 10" across the wide rim, about 5 1/2" tall. The fitter is 2 3/4" across.

This is in excellent condition without chips or cracks. It doesn't appear to be marked at all that we could see.
