Hi, I am looking for some info on this board I’ve had for 20+ years now. My dad bought it used off of some guy in Cocoa Beach back in '88. I can only tell you what the pictures show. It’s an electric duck G&S-It says SL9175. I’ve been told they only came together for a couple years.? Someone told me to post here because a few guys on here used to work for G&S. Can anyone help me get some info on this board? I would like to sell it too. THX
