Ghost in the Shell: CZN-M22 “9 Weapon” Schematics

I believe these drawings were made during and for the production of “Ghost in the Shell” (1995). I suspect they may have been used to build a physical mock-up of the 9-Weapon, perhaps for reference purposes, though I have no evidence of this. Their unusually detailed and technical nature clearly marks them as something far beyond a simple model sheet for animators.
