Two and a half years ago, I purchased a Montblanc 146 pinstripe Solitaire with an extra-fine nib. The nib wrote beautifully; but after a little while, the piston mechanism broke--despite the care with which I had treated the pen, I must add. I sent it to Montblanc for repair, as it was still in warranty. The pen came back with the piston in perfect order; but the nib had been put way out of adjustment. I then sent it to John Mottishaw, who reground it to a true extra-fine of extraordinary quality; and I have since used the pen daily. Well, this evening, the pen, which had been loaded with Montblanc Permanent Blue ink, appeared suddenly clogged and reluctant to write; so I immediately rinsed out the ink, using the piston mechanism, of course. In the process, the piston broke--again despite my gentle handling of it. I offer two questions to the experts at FPN: Firstly, is there some problem with the design and durability of the Montblanc 146 piston mechanism? Secondly, is there a problem with Montblanc's Permanent Blue ink? I should add, parenthetically, that I need to use an ink which will not wash away when exposed to moisture, rain, or spilled liquids; anything less negates the whole raison d'être of a pen, fountain or otherwise, as far as I am concerned. I should have used iron gall ink, except that I had some concerns about the effect of such an ink on the pen's sterling silver casing. I should add that I have had some very bad experiences with Montblanc's repair department in the past. They do make beautiful-looking pens, and sometimes, excellent nibs; but the company does seem to have problems which, I feel, need to be addressed better than they apparently are.
