Here are a few writing samples from me. I bought none of these pens new. For the Montblancs I've relied on the seller to specify the nib size; they seem reasonable to me. I have an MB Fitzgerald in B which behaves just like the 146 pictured below. The Parkers were gifts, hardly used and then discarded by their previous owner. I doubt the 75 really is a medium (as its marking on the feed indicates), looks much more like a fine to me.
The Duofold and 149 are great general purpose writers. I gladly take them to the office. The 146 / Fitz in B really are quite a bit wider and they show a stubbish character, which I like in a broad nib.
Sorry, no relevant Pelikan or Pilot to add to the mix. The M800 EF and Falcon EF are a different game.
