I have owned a Montblanc Heritage 1912 with its wonderful B nib for a little bit under a year now and a few days ago I took a closer look inside the cap and noticed something that resembles rust/corrosion inside at the end of the cap (where the metal rod sits). I hope it is visible in the attached photo.
I have searched the internet for people experiencing similar problems but so far no results. Hence my question to all the owners of a Montblanc Heritage 1912 fountain pen around here: could you perhaps check the inside of your caps for any signs of rust/corrosion? It might be that I am the only person experiencing this (which would surprise me since I have not been using any inks that could cause this and in general used the pen only very sparingly) but it might also be a problem with this particular material inside the cap. I am a bit concerned that a pen of this price would exhibit such a fault.
I am really curious about that and would really appreciate your help!
