See that last answer of mine, Tashclues? You should provide all of the clue in your question in future - other people on the Answer Bank will then be able to solve it for you (because people who have done the crossword aren't always around).
Sorry, Captain2 but requests for further information often seem to bewilder posters (and it is Tashaclues' first time) I think it's worth trying another tack.
Sorry everyone - I assumed you would all have seen the clues. 30 across is 'Rock-cut tunnel of Middle Eastern country? Not one, ten.' 28 down is 'He removed the coins on leaving damaged Greco-Roman box.' Thank you Professor Maisie - I can see I got 33ac wrong and also 27 dn.
