No reserve price - Pipe - Briar, horn

characterful antique briar smoking pipe stamped "Opel Evercool" on the shank, featuring a hinged double-cap wind/moisture-guard mechanism — a spring-hinged outer nickel lid opens to reveal a second inner nickel cap, shielding the tobacco from wind while trapping condensation for a cooler smoke.

Patent marking: "PAT PEND P2361" stamped on the underside of the windcap clip — confirms the lid mechanism was a patented design
Materials: Briar wood bowl, nickel silver hinged windcap and ferrule, ebonite/vulcanite stem collar, genuine horn mouthpiece/bit
Age: Likely early 20th century (circa 1900s–1920s), consistent with the windcap construction, horn stem, and "Patent Pending" style marking
Weight: 73g
Dimensions: 23 x 18 x 4 cm
Condition: Fully functional; small nick to the horn mouthpiece, otherwise sound
Notable feature: Working patented hinged moisture-trap lid mechanism, rare to find intact on a pipe of this age
A solid antique smoker's piece with genuine horn and nickel fittings, plus a documented patent marking — appealing to collectors of early windcap and mechanism-driven pipes.
