                                     This aircraft had been a RAAF instructional airframe (INST.16) up until 1961 and hence its

                                     by Neville Parnell at Maitland, NSW in November 1963.  Geoff Goodall saw it in the hangar
                                     at Bourke, NSW in September 1968 (below).  It is still currently registered to Darling Farms
                                     in Bourke.  Sounds like it might be a topdresser?
