The Wackett Warrigal. Both it and the Widgeon were allocated serial range A12-, and only two of each were built. (Warrigal is an indigenous dialect word for a wild native dog.)
Two Wackett Widgeons (Mk. I & Mk.II) were designed and
built at the RAAF Experimental Station as general purpose amphibians. Two
Warrigals (Mk. I & Mk.II) were also designed as, respectively, trainer and
fighter.
The manufacturer's name, Wackett, referred to Lawrence J.
Wackett, former owner of Tugan Aircraft, and at the time in charge of the
RAAF Experimental Station. Later he would head Commonwealth Aircraft
Corporation, and would remain a driving force in Australian aviation
development for some years.
The Warrigal became the first all-metal aircraft
built in Australia. The two designs were allocated the A12 serial range, but not
given actual serial numbers.
Development of the Warrigal ceased because of
lack of funding. Widgeon Mk.II was lost in Hobson's Bay, Port Phillip, and the
types were deleted from the allocation list by 1933.
