A I mentioned years ago in this thread when we were discussing the Beam Approach I, and many others, flew them at our FTS at Tern Hill with Provost T1 trainers in 1961/62.
They probably shut it down when CFS (Helicopters) took over in early 1962. It was difficult enough to keep a Sycamore or Whirlwind upright during instrument flying, let alone trying to do a self interpreted approach.
