Last 2 photos explain how this bat is dated from the Malta Vault book. . Looks like only year this bat was made was 1966. Rare 35” bat. Louisville Slugger changed their stamping every few years so you can date their bats. Use zoom & view all photos.

I repaired a crack running linear on this bat, use zoom. There’s ball marks on bat as you can see. Bat has use of course. Great bat for collectors of the Brooklyn Dodgers.
