Montblanc Classic #320 Vintage Fountain Pen - 14K Gold Inlaid Nib - Piston Filler Product Details: A classic Montblanc #320 vintage fountain pen from the 1970s. Featuring a sleek black precious resin body accented with gold-plated trim. This model is highly regarded for its distinctive 14K / 585 solid gold inlaid nib (wing nib), which provides a smooth and unique writing experience. This specific piece features a traditional, high-capacity piston filling system (not a cartridge/converter type), a feature highly favored by vintage fountain pen collectors. Condition: Aesthetics: The black resin body shows light surface scratches, minor scuffs, and signs of careful use, but retains a nice overall gloss. There are no personal name engravings. Metal Parts: There is visible vintage tarnishing, oxidation, and minor plating wear on the gold-plated metal accents (such as the cap ring, clip, and the ring around the star), as clearly shown in the close-up photos. Nib: Genuine 14K / 585 solid gold nib. The size is not stamped but appears to be an F (Fine) based on visual inspection of the tip. Accessories: Fountain pen only (No box or documents included). Will be securely packed for transit. Specifications: Model: Classic #320 (Vintage 1970s). Filling System: Piston Filler (Internal mechanism). Origin: Germany.
