The "14K/ct (or 585)" nib engraving and logo on Montblanc's "Classic" series (such as the Meisterstück 144) are characteristic of vintage and older models manufactured from the 1970s to the 1990s. Nib: A gold nib with a mix of "14K," "585," and "ct (carat, or part of the engraving indicating gold)." These were handcrafted by artisans of the time, offering a softer writing feel distinct from current models. This model is a rare fountain pen that is no longer in production. Features: Manufacturer: Montblanc (Made in Germany) Model: Classic Color: Black Precious Resin with Gold-plated trim Nib: 14K / ct 585 Filling System: Cartridge / Converter type ( Cartridge & Converter unincluded) Condition: The pen is in very good, pre-owned condition and has been carefully cleaned. It writes very smoothly. The pen is in very good overall condition, presenting an elegant and well-cared-for aesthetic with only light micro-scratches from normal use and the passage of time, with no cracks, dents.
