Hello,
Hakan Gustavsson suggests that the aircraft was No.8 Sqn Blenheim I L8375 (I agree):

41786 P/O (Pilot) Roy Kingsley FELSTEAD RAF (The pilot of L8375), was an Australian serving in the RAF. He came from the bayside suburb of Brighton, in Victoria, Australia.
I cannot find any notification of a DFC being awarded to 44180 Tom McKenzie MITCHELL RAF. Mitchell was an "Old Haltonian" (29th Entry, Jan, 1934), as his NCO number (566717), indicates.
