I've noticed this in my older mont blanc 164 ballpoint under the clip and now I see it under the new 146 fountain pen with the registered trademark sign at the top right. So what exactly is Pix and I thought someone said here it was only on the older models?

Thanks
Brad

I think it's part of their anti-counterfeit trademark markings. On my 147 that I just got, it has the cursive Pix on the cap band along with Meisterstueck. That's new to me. Usually it's on the underside of the clip.

If I'm not mistaken, some of the vintage MB pencils used to go by the Pix label.
