There were a couple of touches of blight elsewhere on the vine or adjacent vines, and some damaged vine that was rotting, but nothing looked wrong with the truss, vines or foliage around these tomatoes. Three tomatoes had black spots in total. The rest on the truss had no spots and are uniformly red all over.
This is a high resolution photo of the third tomato, which was larger and had less obvious spots:
There have been snails crawling over the vines, blackfly and caterpillars on a very nearby dahlia and probably other garden insects, including bees and wasps (because of the dahlias).
Oh, I've just cut the worst one open, and it seems perfect inside. I peeled back the skin a bit and the black spots don't even seem to be on the inside of the skin, just the surface of the fruit.
