Thanks slimboyfat - yes, a video would be good at some stage. Hopefully if the map shows the locations of former branches, it shouldn't be too difficult to see how widely-spread the organization was at its peak.
Is that only selected branches?
No, these are all the remaining 98 branches. I did consider including "country offices" on the map, but I've decided to disregard these because it is the branch offices figure as published in the worldwide report that is of interest in this exercise, and I don't want to muddy the waters.
I have also been informed that the Cyprus branch has been closed and "merged" with the Greek branch, so that takes us down to 97. If anyone can provide further information on similar branch closures, I would appreciate it! I will be updating the map today.
