manufactured between 1920 and 1929, here in the long version.
The nib has laterally an indentation, the result of a so-called " ruler writer ".
with this over years along a ruler drawn (e.g. the accountant who repeatedly draws lines in his ledger has drawn).

otherwise is the fountain pen in an excellent to near mint condition. Very beautiful imprint, the clip as original Montblanc design, imprint on the barrel still legible, the cap head with the logo still properly white.

A beautiful collector's piece which today, in this condition, is only difficult to find.
