I need help identifying a very old DN

I recently acquired what looks to be a very old DN. It is made mostly of dimensional lumber, there is very little plywood in its construction. All the hardware is galvanized, there is no stainless. The sail is made of sailcloth with several sewn in patches. There appears to be no battens. The sail has the number 78 embroidered onto it. How can I find out who might have built DN # 78? Thanks Fred

Not in the sail-log

I didn't dig out the three-ring binders, but there is no 78 listed in the electronic sail-number log.
