How sure is it
Every result carries its confidence. Treat the year as a strong guide, not proof: a serial can be replaced, a neck and body can be from different years, and reissues copy old numbering. For anything that matters, confirm the year against the neck date, the pot codes and Harmony's date-your-guitar page.
