vintage white milk glass diffuser shade, replacement lamp shade reflector

Vintage milk glass reflector shade for an old Rembrandt or Stiffel type lamp. This is not marked at all that we could see.

It's 6" across the wide rim, about 5" tall. The fitter is 2 1/4" across. This one has a small flat chip at the shoulder of the shade, almost invisible since it's not all the way through the glass.
