What an interesting thread!
The one issue that surprises me is how long the 405 network persisted after 625 had been established. Presumably single standard 405 TV's stopped being produced in the mid sixties, but did new dual standard TV's go on beyond 1969 when BBC1 and ITV migrated and went colour?
I seem to remember the 405 channels being treated as the 'core' network by the broadcasters right up to the end - Eg. childrens TV was displaced to BBC2 on budget day so that BBC1 could carry political coverage.

Maybe the robustness of VHF transmission in comparison with the new broadcasts?

The digital switchover was far harsher.
