Hello NCB3
That's an unusual question there.
We largely know about Scott Bonnar push mowers through
only a few sources...

Grant Simpson's excellent Compilation is the main source.
It depicts the Standard, Ace, Dux, and the Putting Green mower.
Surprisingly, no illustration of the Bon that I researched some time ago...

I have never found any evidence of the Dux beyond Grant's.
However, at least one Putting Green mower survives,
confirming its production.

The second image (below) from Grant's Compilation shows
the South African Agency. The interesting thing there are the
non-Scott Bonnars.

I think that's a Royal Enfield power mower on the left; and the
side-wheels look to be Pennsylvania [USA] mowers.

Do you have any information?

Cheers
