Well put, Jim. Diverting a bit, a friend of mine and his group of amateur divers found a few years ago a couple cannons and an anchor in an underwater place nearby, having only recovered the one bronze cannon and leaving behind the iron one and the anchor. They realized they didn't have the know how and the means to recover the iron pieces without risk of desintegration. I think the two items still reside in the same (rocky) place, some 200 yards from the shore.
On the other hand this cruzader sword looks to be well encapsulated by a dense layer of crustaceans; and will be handled by experts ... assuming inside such capsule there is a real sword .
