Can you check the metal parts to see if there is a name ?? Whoever made the crock would not have made the metal parts too !! They would have been bought according to the size needed !! May have to look with a magnifying glass,, even inside the metal band on the pot !!

looks like minimum 2 gallon

So,, about a gallon liquid or there about !!

16″ diameter 13″ high

Size ??
