Joe Walser, team leader of Time Machine Restoration and co-organizer of We're Going Back helped design the lifesize clock tower clock and the entire line of BTTF products for EFX. It also comes with the panthers.
The answer was the Clock Tower Clock. Congrats @Alric. PM me your mailing address and I will send out the book once it's released in October.
Here is a image Joe recently shared on FB. Even if they are not selling the 1:1 scale version, the miniature replica is a great piece to have.
