Well I have always had a "Thing" for cannonballs. 2 of these were found in a garage a couple of months ago, the older couple contacted me at a military show and told me about them, they have owned the house for 16 years and never knew they were there.
I kept one and my friend took the other.
The DIA in 9 inches, weight well over 100 pounds, so it was a costal gun. The problem with these is that no gun of this size was ever within 100 miles of here.
I wonder how it got into a garage in East Your Ontario. These are not dug up, the only rust is on the bottom of both, where they were in contact with the garage floor for many years.
