Cryptic crossword No 594

I've used the MyC annotations field to explain why this puzzle is a bit unusual. Full wordplay explanations can be found here. http://www.fifteensquared.net/2021/07/15/independent-10844-by-methuselah/

When solving I thought I had missed this the first time, but the annotation reminded me. Regardless, a pleasure to solve for a second time and a very impressive set of clues given the constraint. Hard to choose favourites but I'll go for 12a and 13d. Thanks Methusaleh.
