Cryptic crossword No 2,455

Thanks tpg, that was enjoyable from 'A to Z'. My favs were 12a, 24a, 4d, 14d, and 19d. I couldn't quite parse everything but that's par for the course in my neck of the woods.

I admire the overall construction and I liked 23a, 2d and 17d.

Thanks tpg, nicely done ... and a cheeky trick with 5d to help make it all work. Faves 9a, 12a, 24a, 4d & 19d. Spoilers ...

I do have one question about this grid: can anyone (even those who’ve skipped straight to answer key) tell me whether this type of construction has a particular name? Not a big deal, but I’m just curious and haven’t been able to find it. Thank you.
