Mabie Todd Dip Pen

[Mob Mentality]

Hello all I am new to the forums. I have an antique Mabie Todd dip pen and would like to find other nibs that fit the pen. The Mabie Todd nib that is currently in the pen is expensive and difficult to find. I would like to write with the pen a lot but all the nibs I have don't fit this pen. I recall seeing another post on the forums discussing nib and holder matching. The posted stated that Victorian dip pens had smaller nibs. If anyone could suggest a nib that would fit the pen I'd really appreciate it. I have attached a picture of the pen/nib you should be able to see the nib if you zoom in. Thanks in advance.
