Excellent reading , I'm always learning.

So the big question, how sure are we it's quite old and made as a projectile ?
Happy to post more pics if needed

I guess those (more) elected for genuinity are those rescued from sea wrecks; providing the source that cites them is fully reliable *. Nobody will sink ordinary stone spheres down in the ocean to make them old; something they do by burying them under the back yard earth, preferably near acid fruit trees.

Like those sources that offer cannons as always Portuguese .
