Taily; You may know.
Steady on - I'm not that old! I was at school in the 1950s and in the Land of the Unexpected in the 1960s to the 1980s.
The first DHA-3 Mk. 1 Drover took to the air at Bankstown Airport on 23 January 1948 piloted by Brian (Black Jack) Walker, DHA's chief test pilot.
And Black Jack is no longer here to ask, although he'd fly anything (he had 136 type endorsements.) Black Jack was also the Test Pilot for and flew all 49 Australian built Canberra bombers.
The Drover was intended to be a DH84 Dragon replacement. The Drover would have a robust air frame, let down by being grossly underpowered with the original Tiger Moth engines. Even the Drover Mk. 3 with three Lycoming O-360-A1A engines (180 HP?) would still lack power.
