With the Anniversary Edition 75 Years of Passion and Soul, there are body and nib versions whose engravings do not look exactly like the standard Meisterstück. Thus the Pix imprint on the inside of the clip can appear with an inconspicuous (R) and the cap embossing read only 'Montblanc-Meisterstück-' without the Pix addition. These features are confirmed as correct through comparison with the sister model 144. With remaining doubts, an authenticity check in a Montblanc boutique is recommended, which brings final certainty.
