Yeah, you're pretty close, Fareastdriver.
We had no real fighters at the time, but were producing the Wirraway advanced trainer (a development of the NA16)
and somebody had a bright idea..
What if we cobble together some Wirraway bits and nail a P&W1830 on the front...?
Thus came into being, within a matter of a few months, the "Boomerang" stop-gap fighter.
As an aircraft, it turned out surprisingly well but the arrival of capable American fighters (eg, P40 Kittyhawks) in country, saw it relegated
to Army co-operation and ground-attack roles.
Its armament was two 20mm cannon. (Edit: and 4 X .303s).
BTW, Chris Wren's caricature is spot on.
