I just bought a MB 146 with a 2 tone 14k Fine nib. I am trying to figure out what years it was sold. It has a bluish gray ink window. What year did they switch to the current white striped window? When did they start with the 2 tone nibs?

I am assuming my pen was from somewhere early 90's. Does that sound right?

Any info will be appreciated.

Hi BOBIODEN

The white striped windows appeared in the late 70's on the 146, the two tone nibs were started to be produced in 1993-1994.Otherwise from the late 80's to the early 90's, the MB were marked W-GERMANY on the ring clip and had a monotone yellow gold 18k nib.

hope this helps.

Mine has a Seriel number and W. Germany on the clip ring. How does that help to date the pen?

Thanks for the info Georges.

I would say it is either a 1990 or 1991 pen which were the first to bear a serial number.
