I think, I hope, that I have resolved the missing pictures. These will be replaced gradually over the next week or so, because it is an irksome to repeat a task.
Further ‘Group’ pages and occasional articles will intersperse this chore.
Some of the Group pages have uncertainties highlighted. As noted elsewhere there is no single source that can be called definitive. Many of the passing observations that build the picture cannot be accurately dated. The ‘doubts’ will remain highlighted until they become clear.
