Peterson System Spigot 307 P-Lip, Irish

This record documents a Peterson System Spigot in shape 307, an estate pipe from the celebrated Dublin house and fitted with the marque's signature P-Lip mouthpiece. The pipe unites two of Peterson's most recognisable engineering traditions in a single piece. The P-Lip mouthpiece, another Peterson patent, directs the smoke upward through a graduated bore that opens on the top of the button rather than at its face, a design intended to deliver smoke away from the tongue. The spigot construction adds a third distinctive element: rather than a conventional mortise-and-tenon joint, the stem terminates in a metal-clad tenon that seats into a metal-lined shank cap, a mount descended from nineteenth-century military pipes and prized for allowing the stem to be withdrawn even while warm. Shape 307 belongs to Peterson's long-running System numbering series, a range of bent forms that has anchored the company's catalogue for generations. Dating a Peterson presents a particular scholarly problem, as the firm never employed a factory date-code system on its ; students of the marque instead rely on the evolution of country-of-manufacture stamps and, on silver-mounted examples, assay hallmarks that can fix a year of manufacture. Absent such documented evidence here, the pipe is assigned a deliberately broad bracket spanning the twentieth to twenty-first centuries, consistent with the long production life of the System Spigot line. It stands in the archive as a reference example of Peterson's System engineering in its spigot-mounted expression.
