all i can see is Ur Hen backwards - Ur is the oldest city recorded (i should check that), hence, a hen from Ur.
i have a sneaky feeling that i have totally ballsed it up here. wish you luck.
i think someone is pretending to be me, so ignore that last post.
i've just remembered that, 'UR' is an abbrev. of German origin meaning 'Primitive' or 'Original - as of course, you will all know. hope that helps. ;)
Trevor, you're quoting verbatim something I've already posted. Who's pretending to be you? How can they do that. This is more puzzling than the actual crossword. Hope you get it sorted out. Thanks for your help tonight.
