identification Italo Calvino fountain pen identification

Hello,

Italo Calvino is one of my favorite authors. Just today I happened upon this picture of him using a fountain pen. Can anyone identify this pen based on the photo? The nib appears to be hooded, but for some reason I doubt that it is a Parker 51. I look forward to hearing your thoughts.

Thanks much!

Montblanc 2 digit pen.  The front end looks like a 3x, but the cap band looks like the one on the  1x pens.

@gyasko Thanks for the quick (and confident) reply! I am not familiar with this model and a quick google search didn't bring up much. Could I trouble you for a bit more background on the pen, if you don't mind?

@silverlifterMany thanks for the link! The article was enlightening indeed. I now feel fairly confident that the pen in the picture is a 34.
