Hello Sir Bat

The quick answer is NO.
This is an exciting new find though, and I have some clues.

The mower base fender-styling suggests USA origin.
The single-point height adjuster is rudimentary, and quite unusual
in that height is adjusted from the front.
[Correction: it has a two-point system. See below]

I know of only one mower that used this styling in Australia.
It's the Austral Villiers Hercules -

My best guess at this time is that - if original - this is a privately imported
mower of American origin.

Hope this helps.
