This is a unique torpedo shade frosted, acid-etched glass lamp shade featuring a fleur-de-lis. There are 3 openings at the point of the shade. Not sure of the age, but it's in great condition and I have not encountered the same model before. The fitter size is 3 1/4.
I've photographed a few of the imperfections and the fitter edge features some light wear. Width at widest point - about 5. Fitter opening - 3 1/4.
Thank you for looking, and please check out my shop for antique and vintage treasures! All items in my shop are from an estate.
Naturally there will be some defects/signs of wear/discoloration. I have done my best to accurately portray any of these in photographs, please look carefully.
