The first 50/50 frame prototypes were machined out of a solid block of material. Jon Julio got the first samples on his Majestic 12s.

The Juice System wasn't a thing yet, that heel plate was just for stability and not performance. You can see how short it was.

The original design had a recessed area for 50/50 grindplates, which was eventually scrapped in favor of standardization.

You can see the anti-rivets were designed to use the same hole pattern at the Roces Majestic 12. These anti-rivets were a small hex vs the phillips head we ended up shipping with.

Jon Julio was the first person to skate the frames, here at the Realm ramp down in Costa Mesa. These were the original baseplates, before the Juice System rear baseplate was introduced. (thanks Blade Museum for the DB ad scan)
