Pipe - Briar, Resin/Polyester

Bent Briar Pipe, "Bruyère Garantie"
Marking: Stamped "Bruyère" over "Garantie" on the left shank (French, "guaranteed genuine briar")
Materials
Bowl/shank: Briar wood, dark brown polished finish
Band/ferrule: Nickel-plated metal collar at the shank/stem junction
Tenon fitting: Two-piece nickel/brass screw-tenon — an outer flanged collar seated in the shank plus a separate threaded inner bushing forming the airhole — a common cost-saving alternative to a hand-fitted horn/vulcanite tenon, typical of mass-produced French factory pipes rather than a named workshop
Stem: Honey-and-brown marbled "butterscotch" swirl pattern. Based on the color, translucency, and swirl character, this is almost certainly Catalin or a similar cast phenolic resin styled to imitate amber (sometimes sold under period names like "amberoid" or "amber-style"), rather than true amber (too tough/uniform-feeling to be natural amber, which is fragile and rarely this evenly marbled) or vulcanite (vulcanite is black/dark and oxidizes green-brown, not honey-toned). I can't confirm this with total certainty from photos alone — a hot-water-smell test or a warm-rub test (phenolic resins give off a faint formaldehyde-like odor when warmed) would confirm it destructively-free if you want certainty before listing. I'd recommend describing it as "butterscotch Catalin-style stem (period imitation amber)" rather than claiming genuine amber, to stay accurate and avoid a misrepresentation dispute.
Dimensions/weight: 15.6 × 4 × 3 cm, 28g
Condition (revised from close-up photos)
Chamber/rim: no cake or carbon buildup — consistent with unsmoked or very lightly smoked
Rim shows fine age-related hairline crazing typical of briar this age, plus a small chip/void at one point on the rim edge
Stem shows no tooth wear
Screw-tenon mechanism intact and functional
Age & origin: "Bruyère Garantie" is a generic French quality stamp ("real briar"), used by many small unbranded workshops, commonly linked to the Saint-Claude pipe-making region, roughly 1920s–1960s. No specific maker can be identified from the stamp alone. The polished (non-rusticated) finish and Catalin-style stem point to a 1950
