Not entirely, as I know Co. Derry had/has at least one code with a Z in
it, but I can't remember what it was, and Husband is now back at work.
S was mostly in Scotland, I do know. SI was, I think, somewhere in the
Republic and IZ was - sheesh, I'm thinking Derry City, BICBW!

Annabel, Londonderry had/had IW, UI and YZ. IZ is County Mayo. No SI
allocated AFAIA.
