The last family of pens I plan on covering will be the Classica and the pens that evolved from it, the Miya, Extra and 1930 Extra.
The Classica family are round bodied pens, most celluloid and silver, most cartridge converter pens, all fantastic.
The first in the Classica line was introduced in 1999 and came in three different colors, Charcoal, Turquois and Cinnamon.
The most unique of the three colors in my opinion is the Cinnamon.
Like most modern Montegrappa pens it is cartridge/converter and you can either unscrew the body from the section and fill conventionally or unscrew just the endcap and fill.
There was also a Limited Edition of 1000 pens in each color, Parchment, Red and Black that was called the "Historia". It featured the smaller Sterling silver section (that would later be found on the Miya) and the incised cap band and was the same size as the Classica.
The Historia and the later Extra/1930 Extra look very similar at first glance but the capband is wider on the Extra/1930 Extra and the section and nibs are considerabley larger as well.
In 2004 the second Classica series came out with a resin body in blue, red and gray. On my resin Classica the end cap does not seem to unscrew, or at least not easily and I have never tried to force it. Both series featured the Montegrappa 18K Greek Key motif nib.
The biggest design difference is in the cap bands, the earlier celluloid model featuring a narrow mechanically engraved cap band and the later resin model the wider cap band that is laser engraved.
As mentioned above, the round non-silver body family of pens includes the Classica, Miya, Extra and 1930 Extra. The Miya and Extra seem to have very similar celluloid bodies (different colors) but since the section and nib are slightly smaller on the Miya (the Miya uses the smaller Sterling silver section but the same nib as the Classica) the overall body length and the slope where the body and section meet are quite different.
The Extra was introduced in 1999 at the same time as the Classica and was first offered in Midnight Blue and Parchment. Unlike the celluloid or resin section of the Classica, the Extra featured an all Sterling silver section that was wider and sported a much larger nib.
It also had an imprint on the body that was copied from the pens of the 30s. One other change was the introduction of the incised Greek key design on the cap band.
In 2005 the Extra 1930 was introduced and the biggest change (other than the colors of the celluloid) was that the imprint on the barrel was dropped and a new larger wood box with a bottle of ink added. The Extra and the Extra 1930 are the same size and weight and both seem to be a piston or captive converter filling system.
