Montblanc - Nº 2 (Third Series / 'M 3' - Ebonite) - Fountain pen

A0000005293

We are putting up for auction an authentic archaeological legend of the world’s high-end writing-collection: the extremely rare Montblanc Nº 3 button-filler fountain pen, manufactured in Germany in the 1930s. Crafted in the legendary early 20th-century black hard rubber (ebonite) and crowned by the historic white star emblem of the brand, this historic piece represents the founding foundations and the Golden Age of the Hamburg firm’s engineering, offering a writing instrument of extraordinary mystique, mechanical complexity, and patrimonial value.

The design of this very rare vintage fountain pen is a display of period-era aesthetic fidelity and engineering: the body measures a closed length of 12.8 cm with a stylized diameter of 1.2 cm, delivering unmatched balance, ergonomics, and lightness in the hand. The cap features the classic vintage gold-plated clip with the company name engraved on the silhouette of Montblanc Mountain, preserved in admirable condition. The rear section distinctly bears the original factory seal: "M 3", certifying that we are looking at a body and mechanism from the third original series, extremely difficult to find.

But the true heart of this work of art lies behind its rear thread: when you unscrew the tailpiece, you discover the original brass push-button mechanism. When pressed, it actuates the internal rod that compresses the filling sac, an emblematic system of the 30s that reliably feeds a splendid original Montblanc Nº 2 solid gold nib of 14 karats. This period nib features impeccable geometry and a Medium (M) nib size, offering the flexibility and liquid flow that are unparalleled in its historic performance.

Authenticity Note: The body of the piece corresponds to model Nº 3, bearing a Montblanc Nº 2 nib from the same era, a historically fully functional combination that was very common in writing instruments of the time and which often surpassed years of service in official workshops. A luxury design milestone intended exclusively for serious collectors.

Condition: Collectible Rarity / Excellent Historic Condition
The aesthetic, cosmetic, and mechanical condition of this specimen is Excellent for a piece approaching one century in age:

Ebony Body and Cap: The ebonite structure preserves its original deep black color with magnificent natural patina, entirely free of cracks, fissures, or deep scratches. The historic identity engravings on the tailpiece ("M 3") and the cap side ("Montblanc") remain sharp, clean, and perfectly legible.

Gold Details and Nib: The gold-plated clip retains its fixation and historical shine. The solid gold Montblanc Nº 2 nib is pristine, with no deformities in the tines or welds.

Filling Mechanism (Button Filler): By unscrewing the rear section, the pressure button is firm and functional. The inner sac has been inspected/replaced to ensure optimal ink suction, allowing the pen to be completely clean and ready to write should its future owner wish.

Curious Fact for the Collector
