Peterson St. Patrick's Day 2019, Shape 307, Fishtail, 9mm Filter — 2019 Annual Edition

This record documents a Peterson St. Patrick's Day 2019 pipe in shape 307, fitted with a fishtail mouthpiece and accommodating a 9mm filter. The example arrives from an Irish estate and stands in the archive as a representative specimen of Peterson's most widely produced annual commemorative series. The firm's St. Patrick's Day series, issued each year as a themed annual edition, celebrates Ireland's national holiday and has become a fixture of the company's calendar, typically drawing on established Peterson shape numbers and presenting them in a distinctive yearly finish. Because each release is bound to a single production year, these pipes carry an unusually precise internal date: the 2019 designation places this example firmly within that year's run, without recourse to the hallmark or stamp-sequence analysis that older Peterson pipes often require. The 307 belongs to Peterson's numbered shape chart, the system by which the factory has catalogued its bowl and stem configurations for generations. This example carries a fishtail mouthpiece — the conventional slotted bit, so named to distinguish it from Peterson's famous P-Lip design, in which the smoke channel exits upward through the button. The stem is bored to accept a 9mm filter, a system common on continental European market pipes, in which a disposable charcoal or paper filter seats inside a widened tenon channel; the pipe may equally be smoked with the filter omitted or with an adaptor fitted. As a dated annual edition from a working Irish factory of long standing, the pipe serves the encyclopedia as a clean reference point for Peterson's modern commemorative output: a numbered chart shape, a fishtail bit, a 9mm filter bore, and a year of manufacture fixed by the series name itself — 2019.
