In 1948 Montblanc restyled its  models and introduced the 14X line of pens.

Initially only sizes 142, 144 and 146 in black celluloid were produced. The big 149 was introduced in 1952.

Later on Montblanc introduced a beautiful striped celluloid in two different tones of green and in  gray which was used for all the sizes with the exception of 149 which was manufactured in black only..

Early feeders on these models were flat with two back channels. Later feeders have a bumped back and a different design.

This Montblanc 144 is in excellent condition and it is fitted with a very pleasant stub nib.

The cap has a customisation which reads "Acciai Marathon" (Marathon steel).
