Hi everyone, that might seem like a dumb question but I was wondering if its possible to purchase brand new MB pens 146 or 149 with BB nib?

I can't see any reference to nibs that are not F,M and B when looking at MB pens. There are a couple of options on eBay (a 145, and used 149 both with BB) but for this price point, and being my first very expensive pen Id rather a) buy new and b) be able to test it out first.

Any help is greatly appreciated. If you can let me know the width of a B vs BB that would be even better. Ultimately, what Im after is a cursive italic nib of between 1.3-1.5mm. so starting with a BB should give me good width and I'll send it to someone (probably Pendleton) to get the BLS treatment.

Cheers,
Kelvin
