The South African pressing would have had the same catalogue number as the Zimbabwe pressing but with a different label design.
There may have been some issues regarding the UK pressing plants usually used by Charisma/Phonogram in early/mid '78, because quite a few of these purple-label Irish pressings turned up here at that time. My copy of CB 309 is another such.Comment by pine-monkey:
Just uploaded photos of the UK silver plastic label pressing. Strange that so many Irish pressings have turned up in the UK. This silver pressing seems to be comparatively rare.
