This is a robust, museum-quality example of a WWII British Air Raid Precautions (ARP) Gas Alarm. Crafted from heavy-cut hardwood, it features a spinning gear mechanism that strikes a flexible wooden reed (tongue) to create a deafening sound designed to carry across city streets during an emergency. Unlike lighter carnival versions, this is a "warden-grade" tool built for durability. The handle is securely pinned, and the frame is reinforced with period-correct flat-head screws and washers. A must-have for collectors of Militaria, Civil Defence history, or unique primitive folk instruments.

Material: Solid Oak (or similar dense hardwood), Wrought Iron Screws/Washers, Steel Pivot Pin.

Age: Circa 1939–1945 (World War II Era).

Origin: United Kingdom (British Military/Civil Defence Issue).

Item dimensions: 8.5" tall x 11" long

Condition: Excellent Antique Condition. The wood shows a rich, dark patina consistent with age and field use. There is minor surface wear and typical oxidation to the iron hardware, which adds to its historical character. The mechanical action remains fully functional, producing a loud, sharp rhythmic "clack." No significant cracks or structural repairs noted.
