The change of the engraving from "W-Germany" to "Germany" took place in October 1990, while the black-grip-section variant with solid-gold nib was mainly made in the middle of the 1980s. A plausible explanation is that within a repair by Montblanc the clip or the entire cap was exchanged for a then-available spare part; writing instruments with temporally "mixed" components are therefore not unusual. A subsequent cap exchange by a dealer is also conceivable, especially since the cap of the 144 is susceptible due to its thin material. The writing instrument thus basically remains a real Montblanc but combines components from different production phases.
