What we could not confirm
- The era not stated format is documented but not decodable here: no pattern (no date encoded, or format unknown).
- Sub-Zero is treated as sharing Wolf's format because the source lists it in that family; the corporate relationship itself is an estimate.
- Official answer: manufacture date is printed as a separate 'Date Code' on the tag (position moved April 2020); the serial itself is not decodable by the public - call Customer Care. Building-center's Wolf/Sub-Zero page agrees (no formal coding).
