Some more validity to G40 being the base for the OO Polarized line.
But this kind of loses some credibility, claiming the the G in G30 stands for verde/green, and VR was an accidental mixture of 'violeta' and 'oxido' which produced a beneficial results. Might be where the Violet Rust story came from, and they could be running with it since they seem to not be terribly good about remembering their own history.
