MONTBALNC Safety Pen No. 4 from the mid‑1920s, crafted in black ebonite and fitted with a 14k gold nib, size F, with the corresponding engraving inside the cone. The pen features an 18k gold overlay, applied not in Hamburg but by local artisans, as was customary for luxury versions of Montblanc writing instruments at the time. Several details confirm this piece as an early artisan collaboration: the gold-colored flower set atop the Montblanc emblem, a decorative element never used in Montblanc’s own workshops; the clip shape, which differs from any documented Montblanc design of the period; early Montblanc pens were sold without clips, allowing clients to choose and attach their preferred style; the exact overlay pattern appears in a 1926 catalogue of a Milanese stationer offering Montblanc pens, further supporting its origin as a market-specific artisan customization.
