Perfect Gundam was a orginally came from manga for kids, to lead them buy more models. Artist of manga was a member of modeling team and the team backed uped manga with their idea and techs. So the manga introduced modified comercial model with actual designing and refining, which was accepted as cool thing from kids. Their idea made Perfect Gundam's extra armor right from the point of view of modeler. It is interesting that their work still comes along with this century.
I should've gotten the Gundam Base release at a recent convention when I had the chance, as I've slowly been building up my RX-78-2 historical gallery.
