I have only recently discovered the forum, although I have been doing the crossword for decades, with the only reward so far being a book token, in the days when there was one main prize of a dictionary and five runners-up of the aforementioned token. Now in my eighties, I am definitely slower than I used to be, but I usually manage in the end, now with a little help from the forum. But I am having a lot of difficulty with this one. I got 19,1ac quite quickly and a few others, but the SW corner is a complete blank. There are also still some missing in the rest of the grid. A few more hints would be helpful.
