Heritage & Provenance
The story of this piece
Why it exists
The twelve-faceted Danish design came principally in three colours — brown marble, green marble, and black. A fourth variant exists well outside standard catalogue production: the exceptionally rare Platinum version. This is not the conventional Platinum material seen on models such as the 124PL or 234½PL, but a model-exclusive composition blending silver, grey, and deep black tones.
Why it matters
Among collectors of the Scandinavian production this material is widely regarded as the rarest and most distinctive Platinum execution ever applied to a Montblanc pen. Across the twelve facets the silver-grey pattern shifts and recombines, the wide cap band anchoring the composition — Art Deco structure rendered in a storm-cloud palette.
Why it is rare
An out-of-catalogue material, applied to an already scarce faceted form, in a production chapter that was itself modest — each factor multiplies the others. Surviving examples are seldom encountered at all; with reference-grade imprint integrity they are rarer still. Both cap and knob imprints here are ultra deep and crisp, of New Old Stock quality.
How it survived
Near Mint, with minor signs of use. The flexible 14C EF nib is a smooth writer, tested with light pressure; the push-knob system works fully and holds ink perfectly. Professionally serviced and in full writing order.
Taken together — the rarest Platinum material, the Danish twelve-sided Art Deco form, and reference-grade imprint integrity — a museum-level artefact of Montblanc's Scandinavian chapter.
