It is quite possible I have one from the first production year, 1999, but I am not familiar with the coding on the box.. Also, I have been told that shortly after the initial release, the 'Noir' engraving which appeared on the primary barrel ring, became a subject of possible copyright infringement and the name was no longer engraved on future iterations of this pen. I have yet to substantiate this through any authority.
This is not entirely true. It is still refered to as a Boheme Noir on their web page. As for the engraving, that comes and goes with all MB. That being said, it is a fine pen
