Important Notes

How this was determined

We use manufacturer serial format rules and published industry references to extract manufacture date information from serial numbers. Some brands reuse year codes across decades, which is why multiple valid years may appear. When two years are shown, the correct decade can typically be confirmed using physical condition, purchase records, or known installation dates.
