It's not that they don't know it's old,used lamp It's that they apparently don't CARE it's an old, used lamp . This seller has other lamps listed that ARE new with no discoloration and nice shiny bases and photos of both the sleeve/box AND clear photos of the etch. The fact that only this one has no direct photos of the etch tells me that the seller KNOWS that this isn't what it's advertised as and since they have listed that they don't accept returns probably isn't really concerned either .
Maybe so. Buyer beware as always.
