Looks like the buttons and joystick ball were replaced at some point.
I am pretty sure the serial number plate is a DK red. Another KLOV'r has a red DK that is 3 numbers ahead of this one.
I am not sure having two WF tokens is enough to validate that it was the game at the fair, nor am I sure a game that was at the fair would be worth significantly more than a regular red DK.
