oh dear, I think I might have to give it a miss tonight, brain not doing well, blaming jet-lag,(well, any excuse). Thought of NZ but have googled to no avail for 6d. I have managed to get all of 8 though, an easy one I suppose. Can you give me a clue to 19d? There again I think I've got the connection, but not sure how 19c fits it.
