Thanks, that is exactly it. A photo at the end of the article shows the old airspeed factory. When I moved to the area in 1988 this was owned by Revvo Casters and I had no idea of its actual history. It's currently being redeveloped into something else. One of the commercial buildings on the old site had a sea vixen (IIRC) as a gate guard but that is long gone.
