Judging by the tail (stern) fins it is mid 1950's something. Although you asked for information on the boat, I will offer some advice since I know nothing about the manufacturer, make, or model of the boat. Looking at the pictures it appears the transome needs replacing and I would venture a guess that it was replaced at another time in it's life. The hull is fiberglass or plastic of some sort yet the transome is not so that's my reasoning for earler replacement. All of the wood appears to be in need of replacement and when the floor is removed you will likely find some rotten stringers. So with that in mind, before you do anything else, strip the wood to see what you are dealing with. Weigh the cost of restoration vs what the boat is worth when you are done. If the stars align, go for the restoration and if not, give someone else a free boat.
