I just picked up this 7 foot Jacobs hull. It has a waveset fin which leads me to believe its late 60s or early 70s. The board is basically unsurfed and untouched in great condition. Ive done my research and cant find much about this shape/model. What gets me is the logo on the deck because I have never seen it before and couldnt find a similar logo online. Also the serial number is marked ‘Z - 179’ and I was wondering what the Z meant. Any insight would be very cool!
