Sorry but I disagree. The clue is peers, looks, scans. If it were written "Peer's to own ...." I would agree with you. I expect decent english from the times.
If it were peers then the answer would be "has a butcher's"
I peer = I have a ...
he peers = he has a ...
You do realise that in this clue the apostrophe is nothing to do with the possessive, it is the shortened form of the word 'is' e.g. it's = it is, as simple as that. So nothing to do with ownershop of anything.
This is a cryptic clue; a cyyptic clue usually consists of 2 parts: a definition and a subsidiary . 'peer' is the definition; 'is' implies (in the way that cryptic clues work) that the rest of the clue is the subsidiary. Are you new to cryptic crosswords? because with your pedantry I can't believe you'll stick with them for long. Unless you're (= 'you are', not 'your') clutching at straws because you know that you were wrong.
So the definition and the implication were tied together? This gets better. As I said earlier I bow to your superior knowledge of use of the lingo. If you say the english is good who am I to doubt you professor?
I usually crack these puzzles in about five minutes and have been so doing for about 25 years so do not try to lecture me on cryptic puzzles. Goodbye.
