Antique Signal Cannon
These antique signal cannons are robust maritime pieces designed to make a loud report, offering serious collectors a tangible piece of naval history.
What They Are
When you search for antique signal cannon, you are looking at functional ordnance models and scaled pieces built for maritime and ceremonial use. The selection includes desktop scale models and robust cast examples mounted on wooden carriages.
You are most likely to meet 19th-century brass and cast-iron versions on this page. These range from heavy deck pieces to small desk ornaments produced in later decades like 1910.
How They Were Made
Maker workshops constructed these cannons using durable metals such as brass, bronze, cast iron, and polished steel for the barrels and ordnance bodies. These metallic elements provide the substantial weight required for firing or display.
Carriages and bases were typically fashioned from seasoned timbers like oak and various dense woods. Metal and wood components were fitted together to create stable mounts capable of absorbing the shock of a blank charge.

Some models sit quietly on mahogany desks today, far removed from the deafening maritime salutes of their working past.
What Varies in Quality
Quality rests in the precision of the metal casting and the integrity of the materials. Fine examples display crisp detailing on the barrel and well-turned trunnions, whereas lesser pieces show rough casting marks and crude finishing.
The sophistication of the carriage construction defines the upper tier of the range. Solid joined oak with fitted hardware elevates a piece far above simple wooden blocks.
