In great shape, vintage 5 cup teapot, from stove top to table! The diffuser is lifted or lowered by the chain placement on the lid of the Teapot.
 
This pot does have some water stains consistent to aluminum but can be eliminated with vinegar if chosen to do so.  Minor dings due to age of pot. 
 
Wonderful piece, difficult to find all intact!
