A rare German "Built-in" Pong. This is an "add-on" kit to add to a Telefunken TV Set. This surfaced in Austria. It is not confirmed that this already came with the controllers or if they had to be purchased seperately. Please not that the controllers could only be used for steering the players vertically and to throw in the ball while the built-in pong game system was controlled by the television's remote control! Check also the very nice Telefunken rifle that could be bought seperately.
