I have the grid filled, but unsure of some of the parsing. In particular, 35a is driving me crazy. I feel like I almost have 28a; I figured Aragon has an extra a, but I don't see where the "AV" comes from in the entry. I'm not sure about 23d either. I have a word that is in Collins but not Chambers, which means put a hat on, but again the parsing eludes me.
I found the grid fill much more difficult than last week, unlike many here.
