French Version of the US Steel Pot Helmet. Non-Magnetic Steel. French Steel Pot! Cordon Bleu! No, this one's never seen the inside of a kitchen, just the outside of a tte militaire. It's from the French army and lightly used--no charge for the occasional scattered rust spots. Very much like the old U.S. steel pot, it's made of non-magnetic steel and complete with liner, adjustable head-band and chin strap.
