Hello I have a few old crocks and was hoping someone here could help identify the maker and a possible value

Hello I am hoping someone can help identify the brand of these crocks , the large one that is marked with what I beleive to be the number "12" it is approximately 19 inches tall and 14 inches wide, the smaller one looks to have the number "6" and is approximately 15 inches tall and 11 inches wide and has a round bung hole , I have done extensive online research and can not come to a definite identification, the small crock/ straight sided jug looks much like a redwing. Any and all information,resources etc. greatly appreciated
