Peterson Kinsale XL16 Smooth, P-Lip — Kinsale Series Era

This reference example is a Peterson Kinsale in the XL16 shape, presented in a smooth finish and fitted with the house's signature P-Lip mouthpiece. The P-Lip, patented by Charles Peterson at the close of the nineteenth century, is among the most distinctive bit designs in pipe history: rather than terminating in a conventional slot, the button carries a small aperture on its upper surface, directing the smoke stream upward toward the palate rather than across the tongue. It remains one of the clearest visual and functional signatures of the Dublin firm, and its presence here places the pipe squarely within Peterson's traditional system of design. The Kinsale line, named for the coastal town in County Cork, belongs to Peterson's named-series catalogue and was built around the firm's larger XL shape chart. The XL16 designation identifies a generously proportioned shape within that chart, the 'XL' prefix marking the oversized interpretation of Peterson's classic forms. Dating a Peterson of this type proceeds by line context rather than by factory date code, since Peterson does not stamp production years on its standard briars; precise dating within the marque is normally possible only when a hallmarked sterling band supplies an assay year. In this case the identification rests on the Kinsale series name and the XL16 shape number, which together assign the pipe to the era of Kinsale series production — the late twentieth century onward. Within that span, the honest conclusion is a series-era bracket rather than a single year, which is how the record here is entered.
