I would like to purchase a new fountain pen, not a dip pen, that has a nib like an Osmiroid nib from the 1960's that I used to use in Portland, Oregon. After much reading and reasearch, I bought a Scheaffer Viewpoint but the nib is much different. It does not give the same variation from thick to thin line that the Osmiroid tip did. I would appreciate it if anyone with specific knowledge of this matter could help. Thank you
