The one they are having loose is to be handled by the public and used to show the glide function. The one behind the glass is the final prototype. ...
Bttf123 still makes the best replica of this prop hands down.

I owned one of his boards, it was pretty nice, but what bothered me, was the foam. after some time it had some scratches and white spots, some stripe were loose, so the holographic foil... And it was very vulnerable for dust and not easy to clean...
