Montblanc Patron Of Art Gaius Maecenas Fountain Pen - OB Nib. Bought NOS from Weir & Sons, Dublin, in early 2021, and sent straight to Montblanc on Hamburg for a nib swap from stock M to a glorious OB. Inked once and lightly used by me as a signature pen predominantly, boxed with all its paperwork and booklet, it's still in essentially as new condition. This is a magnificent pen, and one I will miss, but my nib tastes have changed for the narrower so it's not getting the use it deserves.This item is in the category "Collectables\Pens & Writing Equipment\Pens\Fountain Pens\Montblanc".
