This type of shade combo was used on Student Lamps. I believe that the diffuser shade slips on as would the chimney, so this takes the chimneys place but you have to make sure that its a 3-1/4 size or it will not fit.
The fitter size for the diffuser shade is 3-1/4 so make sure that this will accommodate your lamp. ONLY THROW OUT THE BOXES AND PACKAGING AFTER YOU HAVE INSPECTED THE ITEM OR ITEMS AND FIND NO DAMAGE other than what may be noted in the condition report or shown in the pics. SAVE THE BOX AND ALL PACKAGING, PICS OF THE OUTER BOX AND INNER BOX, AND OF THE DAMAGED ITEM WOULD BE REQUIRED. THIS IS PART OF YOUR RESPONSIBILITY WHEN IT COMES TO DAMAGE.
I PACKAGE TO THE VERY BEST OF MY ABILITIES BUT SOMETIMES THINGS HAPPEN THAT ARE OUT OF OUR CONTROL. I list my items as thorough and as honestly as I can - but it is the buyers responsibility to be informed as possible.
Color shades/tones may vary depending on my back round and lighting conditions as well your or my monitor settings. All my items are either older collectibles or antiques and as with anything of this nature there may be slight imperfections due to age or use as well as manufacturing imperfections.
Please view the pics as though they are part of the items description.
