1961 Grumman 12’ Cartopper - Looking for info

[Vwchappy]

Hi All! I’m a boat guy and recently picked up a really cool boat. 1961 Grumman Cartopper 12’. I saw it on Marketplace for $200 and included a 1968 Johnson 9.5hp. You better believe I didn’t delay on that deal! Score! Pretty cool fact about the boat is that the older gentleman that owned the boat was a Cello player for Frank Sinatra which makes this boat and even cooler score!
So, what I am looking for is info on the boat in the form or brochures, catalogs, pictures, etc. Can’t find much about the car toppers at all. Mainly the sport boats and canoes in the Grumman lineup. Does any one know of any of this or even cartopper groups/forums, etc.? When I get something new I get passionate about it and want to know everything. Also there is no ID plate on this boat but I contacted the PA Fish and Boat commission and it did come up from the registration numbers and I was able to register it with no problem.
Here is a video of my maiden voyage with my old 3hp powering it. Didn’t try the 9.5 yet.

Cool looking old boat, those years,I was working at a marina summers and can remember these old boats. From the pics it looks longer than a 12 footer, especially having 3 bench seats and a bow seat, not sure all that would fit in a 12 ft'r. Anyhow thanks for the video, brings back many memories !!

You got a good old boat for a just a few dollars. Too cool. I think it will be way better with the 9.9 on the back. Have fun and let us know if you do any upgrades. Good video as well.
