Here's a 18" 20 quart. I saw a used 20" on ebay. Both of my grandmothers used these for gumbo pots. I inherited one and use it for Gumbo and pot roasting. I got a 20" and can pot roast 3 or 4 specklebellys. I think I cooked 40 doves once in it. Best pot I have and its probably 40 or 50 years old and been used alot. My grandmother used to cook for 5 to 10 farm workers every day.
