Which features speak for a newly acquired Montblanc Le Grand 146 being genuine, and how reliably does the authenticity check by Montblanc itself turn out?

Since counterfeits become technically ever better and circulate in numerous variants, originals cannot be unambiguously determined via one or two individual features but only via the totality of components. Indications for an original are, among others, the presence of various nib widths — counterfeits practically always carry the width 'M' — as well as the correct execution of clip, cap, star and engraving. The authenticity assessment by Montblanc based on submitted photos generally proceeds swiftly and competently; the query about an engraved ID serves here the internal assignment and is no indication of a counterfeit. On this basis, a presented 146 can without problem be confirmed as an original.
