This is a vintage United States Navy (USN) ship's bell, featuring the "USN" abbreviation embossed in bold block letters on the lower exterior. The bell is constructed from a heavy cast metal, likely iron, and is finished in a matte black paint. It retains its original internal clapper, which is suspended from a central loop inside the dome. The top of the bell features a threaded mounting post with a hex nut, allowing it to be secured to a bracket or hanger. This piece shows some wear consistent with age and naval use, including minor surface texture variations and paint wear, but remains in solid, functional condition with a clear, resonant ring. Ideal for military collectors, maritime enthusiasts, or as a distinctive decorative piece.
