Look for blueprints of lenses

 From:  Samuel Zeller
Hey everyone,

I'm currently doing a top secret personal project (no money, all fun) in MoI 3D and I'm trying to find blueprints and cutouts of lenses (photographic, not video cameras) like Zeiss, Leica, Canon, Nikon etc... It can be old or new lenses, I'm also looking for details about the glass itself used in lenses (side cut).

I'm also looking for blueprints of cameras (Rolleicord, Rolleiflex, old leicas)

Any kind of help is greatly appreciated :)
