A very raw nerve! As Andy Robertshaw said to me on the Somme' Take the artifacts you kill the man twice. There is no chance of identfying a person'. That is why when you walk the Western Front, or any battlefeild. Walk gently, you don't know who you are treading on'. A few years back around local boot sales a, well leave the descriptions, was selling rusty helmets, he claimed there were the reamins of hair etc still inside. If this happned in a cemetery there would be uproar, yet some people boast of having obtained such artifacts.
