The clip is the military type. The nib is two-tone, silver and gold. The silver is partly stained black (from ink?). The gold part looks like it was very carefully painted over with a thin, semi-transparent layer of matte white stuff. I can read the imprint through this patina: "Sheaffer's Lifetime". The patina is very soft; a fingernail will easily remove it.
Questions: Is this white patina a "military modification" to lower the reflectivity of the nib? Should I leave it untouched? Why does it just cover the gold and not the whole nib?
