I've just caught up with this thread. May I offer what is intended to be constructive criticism of the anagram part of the clue? The Guardian book "A Clue to Our Lives" suggests that pretty muchy anything passes by way of clue construction, with one exception:
"Indirect anagrams are forbidden. For example, 'Graduate never ordered plant (7) for VERBENA is illegitimate as you have to first guess that graduate is BA before doing the anagram; but 'east' to put an E into an anagram is OK. Just."
I think that applies to your use of Estonia as anagram fodder.
That said, I take my hat off (if I was wearing one) to Terry, for working it out.
