Ok Vox, lets stop it here but remember it was you who started this thread. I almost cant wait for the news you have for us.
And one thing to Ossy: I don't know even one example of an untouched shipwreck which exact location has been released by their founders. Even in "scientific" shipwrecks, with no monetary worth, their locations has been kept secret. I'd do the same. If there is some smarts guys that only with an approximate position of a site try to reclaim the property of that site, imagine what they could do with the GPS position. (Here I'm talking, for instance, about L. A. V., an spanish "treasurehunter" , that claims his rights of finder of "almost everything" lying on the bottom of the Strait of Gibraltar).
About the cannons: on the site there was a number of bronze cannons that were far away of the number of them aboard of La Mercedes. The rest, 17 iron cannons almost corroded to graphite, are impossible to identify. The bronze cannons, even admitting that they were the type of those that were aboard La Mercedes, are also the same type of some other hundreds of bronze cannons that at those times were aboard a lot of ships that sailed the Atlantic every day. There is not a number, mark of sign that ties even only one of these bronze cannons to La Mercedes.
If you read the papers about this case, there is more information about what is not this shipwreck than about what it is.
You and me (a people who visit this forum) know how hard it can be (sometimes even impossible) to positively identify a shipwreck. And Spain tried (and did in a first step) to convince the Court that it is La Mercedes just with a few coins exam and a timeshape coincidence on five bronze cannons, a timeshape that you can find in almost any naval museum in Spain. And I can tell you that all these bronze cannons in spanish museums don't come from La Mercedes.
I hope one day everything will be clear and finally we all know everything about this shipwreck.
