Peterson Donegal Rocky Bent Rhodesian P-Lip, Shape B.5 — Undated Production Era

This reference example is a Peterson Donegal Rocky in the bent Rhodesian form, carrying the shape designation B.5 and fitted with the maker's signature P-Lip mouthpiece. The Donegal Rocky is one of Peterson's longest-running rusticated lines, its deeply worked craggy surface giving the series its name and making it among the most immediately recognisable finishes in Irish pipe making. The Rhodesian shape is characterised by a squat, rounded bowl broken by beadlines at the cap, wedded here to a bent shank and stem — a compact, hand-filling profile with a low centre of gravity that sits naturally in the jaw. Within Peterson's numbering system, the B-prefix shapes denote a distinct family of designs, and B.5 identifies this particular bent Rhodesian rendering. Students of the marque instead read the wording of the country-of-manufacture stamp — the succession from 'Made in Ireland' through 'Made in the Republic of Ireland' forms tracks broad political and corporate eras — or, on silver-mounted examples, the Dublin hallmark letters. The Donegal Rocky line itself has been in continuous production since the mid-twentieth century, so on the identification supplied this example can only be placed honestly within that long production span, its precise era remaining an open question for the archive.
