This is a rare 149 fountain pen manufactured in the 1970s. It features an 18C nib. The nib width is M (Medium). It's a well-balanced width, neither too thick nor too thin. There are many signs of use, and the parts for ink absorption are damaged, requiring repair. Writing with bottled ink by dipping the nib has been confirmed. Please note that this listing is for the pen body only. If you would like the box as well, it can be included for an additional 2000 yen.
