The salvagers who raise World War Two tanks from the dead

I watched were hey were rebuilding a Panzer tank. The tank had been sunk in a river for over 40 years. A fellow was heating some armor plating to dry out muck under the plating so they could clean. A machine gun round buried n the muck cooked off and scared the folks 1/2 to death.

I have watched a special on cable, I think it was the Military channel where they raised some of these tanks from out of water and restored them it was pretty interesting as is this article. This is a great posting.
