Does anyone know the whereabout of records, if they exist at all, pertaining to staff and course participants of 4 E&RFTS, Blackburn Flying School, Brough, for the period 1938-1939? Records exist in the NA catalogue for its successor, 4 EFTS, from 1 January 1940 onwards, but I have been unable to locate records for the period prior to this.

Specifically, I am trying to establish when Plt Off John R. C. Young was posted to the school as a flying instructor in 1938, and when Plt Off John E. Hibbert was attached to the school for a Special Flying Course which ended on or about 10 Jan 1939, when he returned to his Sqn.

Any pointers would be appreciated
