To the first of them, the New Shorter Oxford implies the answer is no, with the definition
oz. = ounce(s)

[nq:1]As for the period after the abbreviation, we've been told that British practice is to not use it, but the above example from a British dictionary seems to contradict that information.[/nq]
My understanding, such as it is, of the UKan full-stop-after- abbreviations policy is that the period is omitted only when the abbreviation ends with the last letter of the word; e.g., "Mr" for Mister,

I think you're right. It's one of the apothecaries' symbols along with that for drams and scruples. See them here:
