Before the 1930s, Lodge made their "Country Hollow Ware" pieces all designated in inches. In the mid-1930s, they began making a more expensive "Dutch Oven with legs", designated by nominal size numbers 7 thru 12. Dimensions for the #9 were given as 11" x 4.5" deep. The blobs at the bases of the legs and raised size number are consistent with Lodge. Remember that an ID is better made when the entire piece including handles, bail attachments, etc. can be seen.
