Identification guide
With Kerr Self Sealing Mason jar dating, the glass jar and a removable lid can come from different production dates.
Record KERR, SELF SEALING and MASON exactly as arranged. Small base numbers can identify moulds. The glass jar and a removable lid can come from different production dates, so keep their marks separate.
Compare the complete side embossing and base with the jar form and closure. A patent reference supplies a design-history clue. Use a documented Kerr logo variant rather than converting a single base digit directly into a year.
