Montblanc Fountain Pen, Model Number Unknown Junk, Possible Repair Needed Thank you for viewing. This is a Montblanc fountain pen that my father used about 30 years ago. I am selling it now due to a house move and decluttering. The condition is poor due to long-term storage, with dirt around the nib. Please consider purchasing with the understanding that repair may be necessary. Please note that I do not have any knowledge of fountain pens.
