I have come across a document that mentions an RP range at Santon on the Isle of Man (near the Port Soderick bombing range) and additionally it said that a Fleet Air Arm ORS Target (Concentric circles) was being laid out as well. This was in July 1945.

Has anyone come across this range or mention of it elsewhere as I am trying to locate all the ORS ranges used from 1945 to 1955.

I have most of the ranges on the IOM located, although Perwick Bay is missing detailed locations.
