AARC, although he began with a bit of a wild ID has it right now. It is a modern (very modern) repro. A poor quality one not made to fire, at least by anybody with sense. No originals had the casting seams showing, they machine turned them after casting. The "cannon" shown by OP also shows a cast in bore which is not found on repros meant to fire and NEVER found in old cannons. Alan M, AARC is 100% correct, most cannons for many years were made from cast iron, even into the civil war. By the early 1800s a count was kept of how many times every tube had been fired and they were retired, melted down, and cast again. There were many horrible explosions of cast iron cannons killing the gun crews and this still occurred during the civil war. I live not far from the ruins of the West Point foundry in Cold Spring, NY where a large percentage of our cannons were made throughout the 1800s and most all of the cannons made there were cast iron. ALL the huge coastal defense cannons used during the civil war were cast iron and you can see them at the restored forts such as those at Charleston.
