I recall decades ago reading a book about Shackleton's journey to antarctica that referenced an English concertina and that it was an Edeophone.            This morning a friend sent me this link to the BBC New magazine website......................and there it is on the shelf, above the picture of a penguin, image 5/15. Somewhat blurry but probably the metal-ended edeophone.          Here is the link.....................reference was made recently on C.net to not posting links here...
