"Sidewinder" had their own uniqueness - I think I still have literature around here somewhere and thought it would be cool to own one when I was younger (their literature used to have great models, by the way, I remember that literature was VERY good advertising).
Now that I see this one in a larger picture, the style on the sides towards the back reminds me of a brown jet boat that used to run around here - but I have no idea what brand of boat or manufacturer it was, not sure I ever knew. It always wanted to race us in the Switzer jet boat we used to run in...and I remember the owner was never happy that he didn't win!
