PART TWO - Specification
The Bon was essentially based upon the Scott Bonnar electric Ace lawnmower,
a smaller version of the Standard design of the late 1920s.

The Bon reflects Scott Bonnar's experience of Shanks' and Green's lawnmowers
they sold (and converted to power) in the 1920s.

Available in two sizes, the Bon had a cast iron frame and an 8 blade reel.
An interesting feature is the double chain drive, indicating this was a top-end machine.

The lift handles on the catcher indicate English influence.
Here is the specification from the same IBC Catalogue held by the Queensland State Library:-

I have just a couple of adverts for the Bon.
The earliest I have dates from early 1934, and sold by the
Engineering Supply Company of Australia [E.S.C.A.],
early sellers of Scott Bonnar in Queensland:-

No examples of the Bon have been found, and that's a pity to us ... for the record
of remembering the history of our most important pioneering firm, Scott Bonnar,
in lawnmower manufacture in Australia.
