The M640 line of special edition pens was initially released in 2007 starting with the models Niagara Falls and Sahara.  This was followed up with the Polar Lights, Mount Everest, Indian Summer, and Eternal Ice.  The final release occurred in 2011.  The M640 line-up all have very similar characteristics.  The barrels are made of metal and the various models have engraving/lacquer/filigree work to achieve their artistic visual effects.  These are heavy pens as depicted in the table below, heavier even than an M800 and nearly as heavy as an M1000.  The pattern on the barrel does not have a tactile feel so the finish of the pen is smooth.  There is a single trim ring at the piston knob and one on the section.  There are two cap bands and the cap top has a painted one chick Pelikan logo surrounded by rhodium trim.  The traditional “crown” cap top is absent here.  The cap clip is also not the traditional pelicans beak but rather more broad and less beak-like.  The cap, section, and barrel are made of matching colored resin.  The furniture is rhodium plated and the nibs are a monotone rhodium plated 18C-750 gold except for the Mount Everest and Sahara which feature a two-toned nib.  There is no ink view window or visualated section and the barrel has a slight bulge in the middle rather than being a straight cylinder.  More information, including a review, can be found here.  1.30ml ink capacity.
