Duncan Indelux SPIRAL Smooth Straight Pot

USD 37sold 2022-10-26 · eBay

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 sample this sits in: Faridunhill has recorded 12 sales of Duncan between 2018–2025 — median $37, most falling between $15 and $48.

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.
