This view from the cockpit of DC-3 VH-AGU shows the wire frame which was mounted in front of the co-pilot's windscreen. This device was to assist the navigator who occupied the right hand seat on magnetometer surveys. The vertical spikes are set at five degree intervals. The photo was taken at Halls Creek in December 1968. The pilot is Dave Brennan. The previously unidentified co-pilot is Colin Henshall (identified by Nev Williams in August 2017).
