Before radios became standard aboard every vessel, sailors relied on voice tubes to communicate between decks and compartments at sea. This solid brass mouthpiece is a genuine component of that system — its flared opening designed to carry spoken commands clearly through tubing routed around the ship.
The mouthpiece includes the original thumb lever / closure flap, used to signal a call or seal the tube when not in use. A polished marine-grade finish highlights tool marks and service wear, preserving the history of life at sea.
