The pen described is actually a 144 from the 1990s. Whether the nib is 14 or 18 carat is for model determination secondary, since Montblanc fitted nibs in both carat grades — decisive are dimensions, shape and fittings. On comparison with boutique models or fountainpen.de galleries, the typical features can be checked well. With ballpoints applies: the only true 'Mont Blanc' ballpoint comes from the 100-year anniversary edition with granite cap; everything else are regular models like the Starwalker.
