That's right, it was YZ I was trying to think of. I think they've
finished the *IWs now and are going through the *YZs? UI is Derry City,
isn't it, rather than Co Londonderry? I remembered this morning that IL
is Co Fermanagh

My 1966 list gives all three as Londonderry. It might have been Derry city
earlier, just as the Middlesex and Croydon marks are given as London.
