The ball posted, with its circa 4" diameter, should weigh about, say, 3 pounds and, if it were an artillery item, would fit in a XIV-XVI century small bombard, or a falcon. I guess too small for catapults, though... like those in Sant'Angelo.
Also i realize that, their construction being too regular, doesn't help supporting their genuinity .

Thanks , great information indeed , one concern I had is that it might be a Mill ball , but I think with those the uniform wear is quite different from the hand tooling marks seen on my ball .

It's located in Australia, I know that a few family members did travel the world a few times , but that's pure speculation if it originated overseas

Mill (grinding) balls are iron. That's what i feared when i gathered by iron ammo.

Old style windmill water pumps used in remote prairie or outback locations for livestock, etc, generally had a speed governor that uses heavy iron balls as part of the mechanism. Some get sold as cannon balls.

Those could be easily excluded by the initiated, as they leave visible marks of their suspension rings.

I recently found these in a friend's yard. I remembered reading a thread about items that could be mis marketed as cannon balls. I live in an area that had many precious metal ore mines at one time. I thought a picture might be appreciated. The measurements are in inches, my apologies to my metric friends.
