Hi. I would very much like to obtain a Pilot 845 M nib. We can work out something for a trade with a great number of pens to choose from both new and old. Many options to trade including Sailor 1911L, Pilot 743 sfm, Inoxcrom Siroccos, Bexley sterling Goldline, USA made Cross Townsends, Visconti Van Gogh and more. Can add cash for the right trade.
