Has anyone come across any references in books, or got any Notams to RAF / Naval Pilots, NOT to use the Lorenz Blind Landing Equipment around and from 31st July 1940 for a Blind Landing / Blind Approach at Royal Naval Air Station Eastleigh (RNAS Eastleigh) called HMS Raven, or at Upavon; Heston; Manston or Ringway?

The RAF Museum don't have any NOTAMs this early and the NAL (National Aerospace Library) who got their NOTAMs from the CAA, say they are missing from November 1939 to around the end of 1945.
