Well, they still haven't shown up, however I did try it again.
And no closer to solving the mystery, as they all arrived post marked in the same way, albeit at different times of day.
The codes are O (outside main PO), I (inside main PO) and W (work).

Yes, so do I! Quite a mystery - I am sure it will never be solved.Delete
