Thanks jolan - best wishes for all things optical (and other, of course).
I did have #1 right. We pondered the others on the way back without getting them, although when I told my wife the answers, she said for #2 and #3 "Oh, I thought of that." Didn't say it, though (to be fair, she thought that there was only one S in ROSSETTI).
My word, the garden did need some tidying. At least one more visit required before the people visit - that is early October though, so plenty of time (for the weeds to grow).
