Indications of an original are in particular hallmarks with precious-metal specifications (e.g. 585, 750, 925 or 950) on the cap area. An engraving of the inscription "Meisterstück" on the gilded tip from which the refill emerges is, by contrast, untypical and rather indicates a counterfeit, since on a real Montblanc usually no inscription is placed there. An unambiguous judgement succeeds best based on clear detail photos of the cap rings, the hallmarks and the named engraving spots.
