hundreds of thousands of boat companies have come and gone in the past 100 years. most that had small manufacturing numbers and disappeared before the early 90s when the internet came along dont have any information available.
do you have the paperwork for it, yes or no. if no, project wont even be worth looking into it
if yes, you need to seriously consider..... is this a project you want to tackle. my estimate of $6000-$8000 still stands as you are effectively restoring 2 hulls and the exterior gel is shot. then on top of that, you will need interior, etc.
