Before I move on to the endgame, can I get clarity on a few issues ...
28a - Either bar once or never? (3) - I see how it can mean "bar" (assuming it ends in T) but not the "once or never" part.
29a - Dictator’s income as stated 5p at a time (4) - My answer is a low value coin but how and which dictator?
1d - Stuffed case of scorer with score voided (7) My answer means "stuffed" as in 'full up' but, as I can't parse it, I'm not sure if it ends in an E or a Y
