What does the inscription Montblanc-Meisterstück-Pix(R) on the cap of a 146 Le Grand mean and is this embossing normal?

The cap inscription with the component Pix(R) is normal on Meisterstück models like the 146 Le Grand and has been usual for decades. Pix is a historical brand name protected by Montblanc, which goes back to the ballpoint mechanism and appears as a trademark-secured addition on the caps. Background can be found in the more in-depth articles on the brand history of the house.
