This is the Philips D6422 vertical cdplayer prototype, one of the 3 vertical cdplayer prototypes Philips made, but never produced for mass production. The other Philips vertical cdplayer prototypes are the Philips CD400 vertical cdplayer prototype, and the 420mm wide Philips F5822 vertical cdplayer prototype. I do not know why Philips never made a vertical cdplayer.
