Montblanc Nib Sizes

[wolseley1500]

I´m trying to complete this table with the Montblanc Nib Sizes. Could someone to help me to complete it or correct it if there is something wrong?

 

Many thanks

[Uncial]

Ef = extra fine

OBB = oblique double broad

BB = double broad

Can't help you with the mm line widths I'm afraid

[thygreyt]

Measurements are approximate because they are finished by hand.

I have a few OBs and all have different line width...

[zaddick]

Your F, M, and B widths seem way to wide if in mm. How are you measuring?

[wolseley1500]

I'm measuring with a calimeter but all the measurements are approximated. As described Reed_thoughs they are finished by hand and it could be the reason of different line width.

I have a O¿? nib whose measurements are 1 milimeter and another O¿? with a measurement of 1,3 milimeters. They could be OM and OB?

I would say more likely your 1.0 mm oblique is OB and your 1.3 OBB if these are direct measurements of the contact surface of the tip. Line widths on paper are affected by more variables (ink and paper characteristics and writing pressure) but I agree with Zaddick your tabulated line widths in the photo are too wide by at least a factor of 1.5 for typical MB lines.

[wolseley1500]

Yes, these are direct measurements of the contact surface of the tip.

I will say that MB pens seem (to my eye) to write a bit "wider" than most other pens (whether ballpoint, rollerball, or fountain pen). I always find myself having to send pens to a nibmeister to get them made even more fine.
