The shaper is Jeff Widener. I think he shaped for Jacobs in the mid 70’s. Jeff seems to shape for Lost now. Still researchingLotsa people slapped 'bolts" on boards back then.
But hopefully someone here will know if Jacobs did capital B Bolts. I kind of doubt it though- Bolt made their own.
Classic shape. My first board was a Weber swallow with the same planshape. Airbrushed to look like uncooked meat. Ironically, your board is far more tasteful.
