The engravings 4810 (height of Mont Blanc), 14 C and 585 are found since the 1930s on nearly all Montblanc gold nibs and provide no dating. The description with narrow silver band on the gold nib indicates a 149; since this is equipped with 14K nib, the piece probably dates from the early 1990s. For more concrete determination, comparison with the Meisterstück section on Fountainpen.de is recommended.
