Have now identified the female in the photograph as Lores Bonney, see: http://www.ctie.monash.edu.au/hargrave/lores_bonney_bio.html However the plane does not seem to be hers, and the other pilot is not Bert Hinkler, with whom she was associated. So I reallly, reallly, realllllly would appreciate it if a RAAF type was out there who may be able to take a guess at the plane. Thanks! Linda
