Grr! still problems in the SW corner. I now have 26d for certain. I have a possible answer for 33a of a nautical nature which, if correct, the clue might have been better worded as "Maybe Cork's holes". My amended 26a is not in the dictionary as such but suggests something that may be eaten (but certainly not by me). There seems to be only one possible amendment to 30a. But they won't all fit together to make a real word in 26d! I'm wondering if my 26a is wrong. I'm just thinking out loud really but if any of this makes any sense, perhaps another nudge?
