Hueymeister, I'm not 100% certain, but I think this aircraft was at the Flying Selection Squadron based at RAF Swinderby from the late 70's until the Squadron closed.
I just found this but perhaps you've seen it before?

I'm pretty sure I have one of those put somewhere safe, carrying messages of goodwill when I left!
