I wonder if any of the previous salvagers of things like the cannons will be able to recognize the newly discovered significance of what they took and capitalize on it.. I imagine the original salvagers probably turned the items around quickly, but anyone who is hanging on to a cannon that came out of the water anywhere around there has got to be curious if it might be that one.
