Coston Distress Outfit container, Coston Supply Co. Inc. (not authenticated)

This is a cylindrical maritime distress signal container made of metal, likely copper or brass with a heavy aged patina. The surface shows extensive wear, oxidation, discoloration, and mottling consistent with long-term exposure to marine environments or prolonged storage. Affixed to the front of the cylinder is an oval metal plaque bearing raised lettering. The text on the plaque reads verbatim: "COSTON DISTRESS OUTFIT FOR LIFE BOATS & RAFTS APPROVED & PASSED BY THE U.S. BOARD SUPERVISING INSPECTORS COSTON SUPPLY CO. INC. NEW YORK". The plaque is bordered by a decorative beaded or stippled edge, and the surrounding metal shows signs of peeling or flaking coating beneath the plaque. The item appears to date from the early to mid-20th century based on the typography of the plaque and the manufacturing style of marine safety equipment from that era, though this is a stylistic estimate and unverified. The identification rests entirely on the legible text present on the affixed plaque. The item is unauthenticated and presented in unpolished, as-found condition with visible surface degradation.

Based on what I can see in the image, this cylindrical maritime distress signal container bears an affixed oval metal plaque with lettering consistent with early-to-mid-20th-century marine safety equipment associated with the Coston Supply Co. Inc. The object displays a heavy aged patina, oxidation, and surface wear. However, I can't verify from a photo whether the container and plaque are period-original, nor can I test the underlying metal composition. Based on the assumption that the piece is a genuine vintage Coston Distress Outfit container, items of this type generally trade in the $150 to $300 range among maritime and nautical antique collectors, depending on overall condition and the decorative appeal of the heavy patina. The value estimate is heavily condition-dependent; while the weathered appearance adds rustic nautical charm, advanced corrosion can detract from interest. If this piece were to turn out to be a modern replica, reproduction, or decorative copy rather than a vintage survivor, the value would drop significantly, typically falling into the $30 to $75 range as a decorative prop. Physical inspection to assess material integrity, construction methods, and the attachment of the plaque would be needed to confirm these details, along with expert appraisal or archival research to establish a reliable history.
