Made in London, England, specially for the South African market, has been around for many years – and is traditionally a firm favourite with farmers due to its sturdy construction and virtually unbreakable Vulcanite mouthpiece. The patented features of the Keyser pipe are the aluminium condensing chambers in the shank and mouthpiece, together with the protruding aluminium tubes from shank and mouthpiece. There being no connection between these tubes, moisture is trapped in the two chambers keeping it away from the burning plug and helping to prevent a damp, odorous plug (the "dottle") being left behind after smoking.
