Good eye, the barrel at the muzzle is slightly bent, must have been dropped sometime in it's life, easy enough to repair if I wanted to, but I am going to leave it as is, this is a signal cannon, not intended to fire projectiles out of it, it's a smooth bore barrel. From what I was told by a old timer that has restored his share of cannons, these were used on naval ships to announce their arrival in port. I am guessing this one to be late 19th century , probably around 1890's.
