The Classica series was introduced in 1999 just before Richemont bought a controlling interest in Montegrappa. The first edition was celluloid and Sterling silver and continued into the Richemont ownership era. This one was made before the ownership change indicated by the "1055 VI" guild stamp on the Sterling silver parts.
Here are the boring details about the pen:
Length closed: 138mm
Body and nib: 130mm
Italian pens like Italian cars simply exude "stilo", and this pen is no exception. It balances well posted or un-posted, the 18K nib which is on the fine end of medium is smooth and responsive with just the right amount of feedback. The lines are smooth with no abrupt changes and the celluloid section is slightly concave to fit and position your fingers.
The second series of Classica pens used resin as a base instead of the celluloid but it is really well done almost MOP like resin.

The Classica is a cartridge/converter pen design and on the celluloid versions a blind cap at the end of the body can be removed to operate the converter. Of course you can also unscrew the section conventionally.
Like every Montegrappa pen I've tried it is simply a joy to use, reliable, beautiful yet conservative, an understated Italian design with flair and "eleganza".
