Almost correct.

My guess is it's bronze. The item seems to be a cannon. While in 1672, iron cannons were commonplace, they stopped manufacturing bronze cannons at least a century ago. But ships cannons got reused extensively since they were so expensive. So it's quite possible that a 200 year old bronze cannon stands next to a 1 year old iron one.
