When the US went to the kevlar helmets, a surplus store in Utah acquired tons of US steel pots, one of the things they ended up selling them to be used as was feed buckets for calves at daries. I picked up a nice Japanese helmet form a neighbour (with a hand painted rising sun) when the Vet's wife told me she was going to drill a hole in the top and make a planter out of it, or let the grand kids paint it camo and use it to play. When I told her that it was a rather valuable helmet, she told me to take care of it.
