I think I would agree with you John, the ear is distinct from the side of the head which is really what clinches it for me. Incidentally, a little anecdote about these little 'joeys'; just after the war, an old friend of my father, now in his late eighties and living in Canada, used to work in the ticket office of a suburban railway station. He said that the poor little things had become so unpopular that you literally handed them back in change and ran because people were in the habit of demanding the brass variety even though they were intrinsically less valuable. Rather an unfair comment on quite an attractive coin I think, but there is no doubting that they were wont to disappear down the back of sofas ans what not. I have a vague recollection from somewhere that they are still legal tender either as a result of being included in the Maundy sets or simply because they got forgotten about at decimalisation, I can't remember which.
