Unless I’m missing something and/or have got it wrong (entirely possible but unlikely given the crossers), 19d is a rather unusual clue and I’m not sure that I’d want to see it more often
I’m told this is the 350th puzzle by the current Everyman. For his 250th puzzle “CCL” was concealed in various places in the grid. The question is whether this puzzle marks the 350 milestone in some way.
