Hansen Gerry Lopez Model

Hi guys, I’m wondering if anyone can tell me who the shapers were doing the Hansen Gerry Lopez models from 1969-1971. I have one with the number 25271, 7.4 under it on the other side of the stringer (which is the size), and a dot on the stringer between the two. Would love to find out who the shaper is, if anyone has an idea?

@thrailkill Hi Bill, hoping you might see this and be able to assist with who shaped it and what year it likely is? Thank you!
