Hi Tony,
There was a Miles based in Co Tipperary around the same time. Somewhere around Borrisileigh I think. My neighbour tells the story of having been taken up in it and is very specific about the make. It was owned privately and operated from a private strip. I know a photo exists-I can follow it up for you. Have you any info on this? Im flying out of Stansted these days so it'll be a couple of weeks before I'm back that direction again.
