Back in the early 1960s, occasionally I would visit a local Amateur Radio operator. He had spent a good deal of WWII in the military and in the tropics as a radio operator. He once told me an anecdote whereby very soon after hostilities had ended and when he was packing up to return to Blighty, he saw a very large hole in the ground, previously dug my excavators, being filled with fully-functional AR88 receivers.
Obviously, I cannot categorically claim that that story is true - but by what I have read elsewhere, it seems more that just a distinct possibility. Some would say that that action could constitute a war crime - and just to avoid any misunderstandings here, that's not meant to be a humourous remark either, nor necessarily my own opinion.
