[mrz3]

Wondering IF there is a printed chart somewhere with pics that would make it easier to identify specific model of

Montblanc fountain pen.. I think I have acquired a 146 has a serial number , says "germany" and words

Montblanc Meisterstuck Nib is two toned... Also is there a way to specifically determine the Nib size i.e. B,M F etc

thanks...Mike

Hello everyone, thanks for all your answers, the model is a 146, the seller sent me the measures. and is slightly shorter than the 149 and is considerably thinner too.
