Thanks for the comeback, but there was a split years ago within the company and Beetle Cats are no longer made by the original company. No records are available from the company. My only hope is that there are other owners out there who may have information.
What does the flyer say about it? Do you know what type of rig it originally had?
An approximate year would help.
I'm just surprised that a Beetle archive doesn't somewhere. They were certainly among the pioneers of plastic boat contruction. (Carl Beetle in in particular, though I know he sold off the boat buildling company in the 1950's.)
