Detailed indications for counterfeit recognition are found on fountainpen.de under 'Beware of Counterfeits' and in the PDF 'Counterfeits of Solitaire Meisterstücks — A Comparison', in which typical features e.g. on all-metal writing instruments are clearly documented. Reporting the auction to eBay by non-holders of the trademark right brings little; more effective is reporting to Montblanc as protection-rights holder, who gladly accepts such hints. A coordinated forum report is seen reservedly by the forum operator, since this is a private collector site and not an official Montblanc portal.
