Dunhill Rollagas Pocket Lighter, Silver-Tone Vertical Fluting — Scholarly Analysis
Extended scholarly study of "Dunhill Rollagas Pocket Lighter, Silver-Tone Vertical Fluting" (accession JCA.2026.067): material analysis, authentication methodology, comparative works, and bibliography.
Extended description
JCA.2026.067 is a Swiss-made Dunhill Rollagas pocket lighter approximately 2.5 × 1 × 0.5 in. and 76 g, with silver-tone plated brass, vertical ribbed/fluted surfaces, hinged cap and side roller ignition. The base reads “dunhill,” “MADE IN SWITZERLAND,” and “US RE 24163 PATENTED.” The flutes retain darkening/residue while base and high-contact areas show scratching and oxidation.
Technical analysis
The vertical fluting is a case finish over plated brass; the refillable butane mechanism belongs to the Rollagas engineering family. USRE24163E documents Zellweger’s 1956 filling-valve architecture. A technical record should photograph the case machining, plating transitions, roller, hinge, burner and filler/flame-control system independently.
Authentication methodology
Brand/Swiss/patent marks, proportions, roller ignition and mechanism layout support authentic Rollagas identification. Compare JCA.2026.057 and JCA.2026.063 for fluted-case consistency while preserving differences in plating, dimensions and individual wear. Seek any small production/date code in future macro documentation.
Comparative works
Dunhill’s official Rollagas history and USRE24163E establish model and valve context. JCA JCA.2026.057 and JCA.2026.063 are direct vertical-fluted internal comparanda in gold-tone finishes; JCA.2026.064–JCA.2026.066 demonstrate other case treatments and hinge configurations.
Provenance
Acquired in a group lot of vintage Dunhill lighters. Earlier ownership, retail date, packaging and service history are undocumented.
Historical context
The repeated Rollagas architecture across different finishes illustrates how luxury goods combine standardized engineering with surface variation. The Cabinet comparison should foreground that design system rather than treating each finish as a separate technical model.
Conservation history
Recorded fully functional. Preserve the silver-tone plating, fluted channels and base stamps; avoid abrasive brightening. Keep unfueled where practical and document any future seal/flint maintenance. Surface oxidation should be assessed before cleaning rather than automatically removed.
