That is a great model there MadMeex. I particularly like the spar torpedo. 
Have you ever read Clive Cussler's book "The Sea Hunters?" In it he describes the story, in a fictionalized form, of what happened the several ships, and then the real life search for the ship. Here is one passage.
 "Satisfied that they had found the Hunley, they returned to port, drove to the museum in Charleston, and stood gazing at the the sub's replica. "Do you realize", said Ralph, "that we're the only three people in the world that know what parts of the replica are incorrect?"
If you haven't read it I recommend it.
