Butz-Choquin Capitan 70 Dublin, Oval Shank — Modèle Déposé No. 914.8583, French Estate

This reference example is a straight Dublin from Butz-Choquin, presented in a smooth finish and distinguished by an oval shank — a refinement that softens the Dublin's angular character and demands careful symmetry at the drilling stage, since the airway must remain centered through a non-round cross-section. The Dublin itself is one of the oldest codified shapes in the canon: a bowl whose walls taper outward from a narrower heel to a wider rim, producing a chamber that many smokers associate with an evolving flavor progression as the tobacco burns downward. Butz-Choquin occupies a significant place in French pipe history. The brand's output has ranged from workshop-grade series pipes to more elaborate lines, and series names such as Capitan 70 — the line stamped on this example — were used to organize its catalogue offerings. Dating rests on the stampings rather than any factory code. The pipe carries the designation 'modèle déposé' with the number 914.8583, a French legal formula indicating a registered design; such numbers protect the model's form and are useful for identifying a catalogue line, but they do not encode a year of manufacture. Butz-Choquin, like most French makers, did not employ systematic date codes, so an individual pipe can be bracketed only by its line name, styling, and nomenclature conventions. The '70' in the series name is suggestive of a mid-century-onward catalogue designation, but on the evidence recorded here the honest conclusion is a twentieth-century French production of undetermined decade, documented as an estate example within the marque's Capitan series.
