I can see (st)RAT(ford) but whenever I've seen this "uncovered" device used in the past, the answer has always been in the middle - is there something else going on?
Brendan, I think the Rat clue is not very good, but technically OK. Stratford does get 'uncovered', it loses lots of its outer letters - but it's not as neat, good as it could have been. I've seen similar clues before.
