PART 3 - The Grassbox Article

So, taking into account all three pieces of evidence, I have concluded that the
lawnmower in PART 1 was a Scott Bonnar Army machine - a Queen City with a BIG motor.
The clues jogged my memory of an article I once read in the UK's Old Lawnmower Club Magazine.

That article, by Warrick Hanstead, is reproduced below:-

Why did Scott Bonnar use such an ill-suited engine? The answer is simple: wartime.
No British lightweight engines were available, and no Australian manufacturer made small
(and lightweight) engines suitable for lawnmowers.

However, small Australian-made stationary engines were being manufactured for essential
production in farming and agriculture, and the like. Scott Bonnar just "made do" for the war effort.

The photos of the Buzacott 2 h.p. engine in the magazine article show a modified motor (as the article says).
To give you an idea, here is a photo of what I think is a similar engine: note how the fuel tank sits lower,
as in the picture I presented in PART 1.
