Hello Everyone, first post here and already asking for help...
How to identify wich PEN does my MB treveller has?
The box says 147 M, but I remember changing the pen to a thinner one, so it is thinner than a M. EF or F...

The box:
MEISTERSTUCK TRAVELLER
Fountain Pen with :eather Travel Case
147 M Black
Made in Germany
Ident.: 12090

It is from around 1.997

Posting a photo of the nib would help.

Same as mine..if it takes only catridges, then its a 147. The nib is also an M just like mine.

I am pretty sure thats the pen is not a M, cause it had a M and I switched to a finer one.

Hiya m8 that is an extra fine its just a good one. Because the nibs are hand grand they are done in a margin. May if the nib is between this and this it’s a fine and so on. That’s how mont blanc work on that point if I am not Wong I am sure your nib say 18k. ir does it say 14k was it mont blanc who exchanged it for you.

It was mont blanc that changed my nib, it says 18k, I am asking because I am going to buy a newer one I want exact the sane nib, its prerfect to me, but I tought it was a FINE one not an EXTRA FINE.

Well that pen only should have a 14k nib not an 18k so that was a mistake but deeply in your favour. So you will not get as good nib in the same pen unless you get a 146 in the solitaire range
