TOPIC: Need help with a Year

Hello being new here I guess I'll just throw out a bottle and hope. I have two classic glass inboard/out drives and have come across a rather older what I think is a runabout outboard fiberglass boat.
The boat is about 12+ feet long, 5ft wide with fiberglass formed front bench and two smaller fiberglass formed side jump seats. Many many coats of poorly done pain on her and sadly a hole in her hull about 11 inches long and 6 to 7 inches wide. haven't gotten picture of her yet but removed for safe keeping the builders plate (as seen below)
Any help with how old she is and what year would be great help. And if she's worth the time to save.
Thanks in advance..

Thanks for the info, looking at the boat hull shape and over all look and the makers plate and low serial # could place it older then 1956. But will have to dig more now with the info from you.
Thanks I may have to spend some time giving this little gal a new life on the lakes around here
