Hey everyone, happy Friday! simple question today, will a MB 146 nib fit the Bock housing in this pen: https://www.schondsgn.com/collections/fountain-pens/products/fountain-pens I am selling a nib of mine that I have in a Bock (250?) housing, the housing that fits a Conid Minimalistica or Regular. I am by no means an expert in anything Montblanc, or Bock, so I am just looking for some assistance here. thank you in advance, and info helps. have yourselves a great weekend!
