Bushmills was blown up by the IRA. Stavanger Consul was still in operation in the mid nineties. The Aerad book even had the instructions on how to use it. A few pilots, including me, used to while away a Shetland Basin trip checking the bearings. The co-pilots would look at you strangely whilst you were counting the dots. The book didn't mention the Brittany one though.
I believe it was intended for Uboats who could send up a floating aerial whilst submerged and work out where they were.
