Dutch Ovens Help ID with date

[Russ P]

Found these 2 dutch ovens hanging in ceiling of old cabin. They are not too old but would appreciate as precise date as possible

Assuming the Griswold cover and pot are a match, around late 1920s, as their covers starting in the early 1930s had the "Clean Easy" porcelain coating. The Lodge is after 1993, but not sure when the lid marking went from raised to incised. Lodge used illustrations rather than photographs in their catalogs well into the 2000s, so details like that aren't easily determined, although it's safe to say before 2005.

Would you guess that the bottom of Griswold pot would reveal some marking if cleaned up? thanks for your help.

Could be the same TM as the lid, or the previous iteration with the "slant" logo. There was apparently not a big concern with updating patterns all at once.
