Here is a picture of 3 tanks.. I like to think of it as the old western movie.. "the good, the bad, and the ugly"..
Salt was used as an antiseptic at one time, it prevented infections in cuts..
Theres a restored Schneider tank also, but I don't think it was shown with the other three.. here's a video of it..
