vintage replacement glass hurricane chimneys, old oil / kerosene lamp parts

Lot of three vintage glass chimney shades for oil or kerosene lamps. These are big diffuser type shades, with the white frosted shading over the lower part of each shade, to soften the glare.

The shades measure 12" tall, 4 3/4" and 2" at either end. All have a little bit of light scratching to the finish, none have chips or cracks.
