This is a Montblanc Meisterstück 149 with a 14C nib. I believe it's from the 70s or 80s. I'm not sure of the nib width, so I've compared it with a 60s B nib and a 90s M nib for your reference. The ink used is Montblanc Mystery Black. It hasn't been used much, so I think it's in good condition. Thank you.
