Merlin Simulator
I think the Merlin simulator referred to is not the military helicopter, but a simulator built for flight research and design exercises at universities and constructed by Merlin Simulation who had a manufacturing facility, i think, in Sussex. I think John Farley, the former Hawker test pilot, was involved, with students designing control systems and John assessed them, apart from the students trying themselves. I did have a small amount of publicity from them that I picked up at the 1988 (?)Farnborough Show which I may still have it in the loft.
