Can someone tell me what these numbers are for?

now i am confused about tootsie rolls also , what are they and how to get to the centre haha

What’s the distance between fins… Looks like an old board due to the old fcs plugs.  Maybe is a adjusted version of the old McKee set up .  Maybe 11 is the distance between rear fins @ 4 up?

Very well could be the case.

I thought those numbers are what you transcribe from the order sheet. Am I to understand you guys actually try to get the board size to the numbers on the order sheet?

Thankfully there is a ban on all calipers to the general public in Hawaii. Unfortunately open caliper carry has been upheld by the U.S. supreme court.  Will the symbol +/- .25" be added to all surfboard marking now???
