Trying to find a ~ 30 qt. stainless pot that has a lip (as opposed to straight sides) that measures 13.5" to the OD of the lip and 13" tall. Nothing fancy. If anyone has any leads, searching the web has been less than productive.
This one on Amazon says the product dimensions are 17x17x17 which makes no sense for a 30 qt pot. Lo and behold, somebody in the reviews says it's actually 13.5" W x 13" H. Sounds like what you're looking for.
