Lodge cast iron identification
In Lodge cast iron identification, older unmarked Lodge forms can have a heat ring interrupted by notches, including a three-notch arrangement.
Notches and size letters
Older unmarked Lodge forms can have a heat ring interrupted by notches, including a three-notch arrangement. A size number and letters such as SK identify product information rather than a calendar year.
What to check next
Compare the full base, notch positions and handle with documented Lodge forms. Do not assign an exact year from a notch count alone. A modern skillet logo and an older unmarked heat-ring form belong to different mark groups.
