This is a Montblanc 144 fountain pen that came up during the clearing out of my grandfather's belongings. Apparently, it's not a very popular model, so I'll be listing it on Mercari. It has 14k gold-colored trim. No cartridges included. It doesn't have a case, and the ring on the nib section seems to be deteriorated (rusted). I'm a novice, so I welcome any questions or consultations.
