Were there any other store brands in disguise like Victa Monaro?
Two from the late 1970s early 1980s era I have come across that I suspect were at least non dealer retail models like the mid price positioned high arch Pace mentioned, were the low arch Victa Commodore and the 125cc Victa 2 Stroke High Arch and possibly the Victa Corsair (which I believe ended up being the same as the Victa Corvette at the end).
It would seem that the mower dealers in the "Monaro era" only sold models from the official Victa catalogue such as the Corvette, Silver streak, Mustang and self propelled model.
There was also the MSAA mower dealer store branding to add to confusion, as well as Victa catalogue models probably available in some non dealer outlets.
It was certainly a different era back then.
