I believe this a third variation from the 1920's. They had a dark version and a light. This is the light version. May fit Aladdin or other oil lamps.
I'll give you all the dimensions you'll need.. 10" fitter base, height is 7", top measures 4 1/2" to outside edge, inside throat measures 3 1/8". Lamp bulge is 11 1/4. Shade weights just over 2 lbs. Very attactive lamp shade with nice color and design.
A few rough spots on top inside edge. Bottom edge has a few fitter marks. No crack or paint chips.
