Hi JossyP
22a - remove last letter from 'someone gasping' (e.g.. a smoker), include then usual abbreviation for 'old', and definition is 'seat' - something you might sit on. I remember references to these when I was young but not recently!
I am stuck on the NE corner (4,6,7, D 11,15, 19A), so perhaps you might give me a gentle hint or two? Thanks.
