All are round--enamel on cast iron. Lid of same material.
Handles are two loops (one on each side). This is not
brand-name or high-end stuff. It is for general-purpose
use/cooking.

The one I want is approx 6.25" ID and 4.5" inside height.

Holds about 9 cups liquid (measured it). This is my most
commonly used pot for making a variety of things.

It is part of a set that I got a long time ago in Munich.

The smallest pot in the set is the same diameter
(interchangeable lids) except it is about 2" inside height.

I have been searching local stores and on the internet--but
have not found anything similar in terms of the small
capacity, size (height/width), and construction.

Smallest I have found is about 3.5 quarts--which is way too
big. Generally, anything smaller than 3.5-qt has a long
handle or has the wrong diameter and height.

Any recommendations where I can find what I want?
