Hap Jacobs Board 7-4 Need Identied

Found this 7-4 Jacobs single fin in a barn in West Barnstable, MA. Plan to fix the fin and surf it. Can anyone provide information on possible year, shape or how it might ride?

Thank you,
Mikey B




1968,  it’s an original Jacobs made early in the transition period.  His “Hap Jacobs” label was on the later boards that he did starting in the late eighties.
