welcome aboard
without paperwork, and the condition the hull is in and most likely the reason it was stripped is that it is now a yard planter
that is a cored hull. the cost to bring the hull back to safe shape will be significant cost and time. not to mention you need upholstery, rigging, and a motor. you are looking at about $7k and that includes a $100 motor that may be junk
as for manufacturer, could be an old hydrostream, could be an old tahiti
look thru the fiberglassics library.

however as a project, it would cost you more than buying a working boat would.
