I meant to say earlier that this was really good fun Neil, and educational. It got me studying in greater detail to determine the origin of the eyes. Many thanks for taking the time to create a really interactive thread.

Well Planesman, so sorry not to see you at the Elsecar last weekend; I had your prize with me, but have instead given it to "Fireman Roger" (sure you'll know who that is!) to pass it on to you! I think you might need to jog his memory though! Hope you're doing well anyway.
