From 1 recorded sale — this pipe, this day. A single transaction is not a market price, and we will never print one as if it were.

The date shown is the date of sale, not the date this page was published. Our own transaction record, published free. No buyer appears here — not a name, not initials, not a country. Counted across both of our channels — eBay 2015–2022 and Etsy 2022–2026 — so the series is continuous and a change of marketplace is never read as a change in price.

• Not yet measured on this example: length, bowl height, chamber depth, chamber diameter, bowl width, weight. Measurements are added to the record as examples are re-handled.
• The attribute checklist is open on: topped. These are facts, not opinions — anyone holding this pipe can close them.
• Stem material is still open on this example. Vulcanite and acrylic age differently, and it is the first thing collectors ask — if you own this model, tell us what yours carries.
• The stampings and attribution here are as reported with the piece. A second, independent source — a catalogue page, a dated advertisement, a hallmarked sibling — is what would raise this record.
• No factory date code or nomenclature stage has been read on this example, so the era stays deliberately wide rather than guessed at.

Nobody leaves empty-handed. If you hold the catalogue page, the dated advertisement, or a hallmarked sibling that closes one of these — or simply own this model and can measure yours — send it in. Contributions are checked, credited to you by name, and the record is updated with the date it changed.
