RTE had one up in Mullaghanish transmitter station. Remember seeing it regularly years ago. Used to be serviced locally in Eugene McCarthys garage in Ballyvourney. (Kvinyl might remember it too) There was one used in The Shining at the end of the movie when Olive Oyl made her escape.
I have a matchbox one somewhere in my parents house, although, condition is nowhere as good as this one!
