There was a 1-11 at Edinburgh for quite some time. A pointy nosed one, presumably used by Bae for radar work or something of that sort. Used to see it from time to time, but not for a year or two. It was blue underneath, and I think red topsides with roundels. I seem to remember it being in the static line up at a leuchars airshow at one point.
