Wrought (!) and cast iron cannon balls, 16th century

[Will M]

The 24 pound cannon ball on the far right was fired in 1760 at a French fort on an island near Montreal Canada. The broad arrow marking was discontinued around 1800.
Left is a 24 pounder, a 12, a fuzed 24 and the 24 pounder from 1760.
The small cannon ball was found in a bag of coffee beans to add weight, my uncle gave it to me when he was with Nabob.
