Below you will find a detailed accounting of all of the known variations of the Pelikan M3xx family of fountain pens.  Click on any heading to be taken to that model’s respective page which consists of detailed lists, descriptions, and pictures of many of the documented pens.

M300

Originally released in 1998, the M300 fills a unique niche in the Pelikan line-up.  They are the youngest and the smallest of the Souverän line by a fair margin.  Even the M1xx of the Classic series, a smaller pen in its own right, dwarfs the M300.  Since they were released after 1997, there is only one trim style to be found.  There are two variants in the M300 line, both originally released in 1998, the green striped and solid black models.  These pens have a black piston knob, section, and cap.  There are two cap bands, a trim ring at the section, and two trim rings at the piston knob.  The furniture is gold-plated.  The cap top has a painted two chick logo from 1998-2003, a painted one chick logo from 2003-2010, and a 24K plated one chick logo cap top from 2010 to present.  The nib depicts the Pelikan logo and is a two-tone 14C-585 gold.  The nib is user removable like the other Souveräns but, due to its small size the M3xx nib does not swap between other models.   The barrel exhibits transparency on the striated model to allow the ink level to be viewed while there is an ink window to accomplish this on the black model.  Total ink capacity is 0.65ml.

M320

The M320 was first introduced in 2004 when Pelikan gave us the Orange Marbled variant.  This was followed up with Jade Green in 2007, Ruby Red in 2010, and Pearl in 2011.  These pens maintain the same M3xx form factor but introduce some rather colorful and exotic finishes.  There is only one trim variant.  The pens all have a black piston knob and section except for the Pearl model whose piston knob and section match the coloring of the barrel and cap.  The caps of these pens match their respective finishes.  There are two cap bands, a trim ring at the section, and two trim rings at the piston knob.  The furniture is gold-plated.  The cap top has a painted one chick logo on the Orange Marbled and Jade Green Models.  Since the Ruby Red was released during the year Pelikan transitioned its Souverän line to the 24K plated cap top, you will find examples of both in that model.  The Pearl release is only found with the 24K plated one chick logo cap top.  The nibs of these pens are two-toned 14C-585 gold and can be swapped with any nib of the M3xx line but not amongst other lines due to its unusually small size.  The barrels on all but the Pearl model have translucency that allow you to gauge the remaining ink level.  Total ink capacity is 0.65ml.

M350

The M350 was released along side the M300 in 1998.  It followed the M650 and M850 which was released the year prior.  This pen only comes in one color, black with a gold vermeil cap.  These pens are distinguished from the black M300 only by their vermeil cap.  To produce vermeil, the manufacturer bonds a thin layer of very pure gold to an underlying silver base.  The cap band is stamped “925” denoting 92.5% pure sterling silver.  Like the black M300,  the pens have a black piston knob and section with a green translucent ink window.  There are two cap bands, a trim ring at the section, and two trim rings at the piston knob.  The furniture is gold-plated and the crown cap top depicts a painted two chick logo.  The pen has a 0.65ml ink capacity.
