**10.520 Kg**Heavy Victorian Era 1” Bore Cast Iron Naval Type Signal / Early Firework Launching Mortar Cannon Marked ‘IM’(NB NOT FOR BALL). Sn 23300 - 23300 Victorian era iron signal mortars are small, heavy cast-iron device designed to launch signal flares or early fireworks, primarily for communication or celebration. In the 19th century, these "pyrotechnic mortars" were commonly used by the navy or merchant ships to signal other vessels or ports using bright flashes and loud reports. Our original example is in the typical short, squat mortar cannon form with a large 1” bore muzzle opening and has an open touch hole at the base for ignition (the bore is open all the way to the touch hole, illustrated). Made of heavy cast iron, our example is 10.520 Kg weight to withstand the pressure of gunpowder charges without needing complex recoil systems. These mortars were loaded with a small charge of gunpowder and a pyrotechnic "shell" or flare. When ignited, the device produced a loud "bang" and a bright white or coloured flash. The mortar with stubby cannon form barrel is just under 8” height and the base plate is 8 ¼” diameter. One side of the barrel has cast marking ‘IM’ (unknown worthy of further research). The muzzle has lost some metal from one edge during its lifetime. The Mortar is an antique signalling piece and not for ball. The price includes UK delivery. Sn 23300 (armoury floor near drawers)
