In the 1950's Montbanc introduced its line of 14X models which were manufactured in black celluloid with striped ink window and in lined celluloid without ink window. Colors of the lined celluloids were green and gray. 

Green models were manufactured in two different shades of green, light green and sage green, the former being rarer than the latter, and gray, which is even rarer.

Next to the two shades of green and gray, there is a third shade of green which is much darker  and by far the rarest color to find.

This Montblanc 146 in dark-green-striped celluloid is in excellent condition and is fitted with a beautiful and very flexible two tone nib. It has a flat feeder which places it in the very early production line. The star on the cap top is slightly ambered which is an add on to the originality of the pen. 

The pen comes with a wondrous dark green faux leather Montblanc box.

Definitely a grail pen!
