Up for sale is a beautiful, highly unusual piece of turn-of-the-century nautical history: an antique maritime hand-pump plunger fog whistle (deck signal horn) dating between 1895 and 1915.

This heavy-built pneumatic signal device features a massive heavy brass compression cylinder with a turned natural wood T-handle plunger rod. Forcing the plunger down shoots high-velocity air directly through the bottom pipe manifold and into a matching solid brass pipe whistle, delivering a sharp blast. This premium variant is highly collectible because it features an integrated, cast three-legged footed base at the bottom, allowing a lookout or captain to brace it firmly on a flat wooden cabin top or bridge deck during heavy weather.

Condition: Beautiful, untouched cosmetic condition. The heavy brass and copper body has developed an incredible, fiery orange-brown heat tarnish and dark weathered patina from real-world exposure. Does have a broken mounting foot.  Plunger rod moves up and down freely. Piston leather gasket is dry from storage. This does still work, but lets a lot of air through first. Sounds like the most typical tug boat whistle you can think of.
