Wish I was in the area.  Was able to go through the U-505 several years ago.  It has some family history too it.
My great uncle was part of the 8-man team that clambered aboard and helped keep it from sinking.  Before anyone else was able to get aboard, they had gone through the boat and taken a couple of souvenirs.  I have held the captain's pistol and a rifle that he had taken.  Unfortunately, he is gone now and so are the guns.
