This 11 1/2'', 9 cup, aluminum pot has a perforated can that sits on top of the pot and strainer. Hot water trickles through the holes over the grounds and into the pot for a tasty, drip brewed cup of coffee. A clip holds the water reservoir in place. When the coffee is finished dripping the strainer and water can can be removed and the lid set in place to pour a cup. This aluminum pot is in very good vintage condition.
