PART 5 - Scott Bonnar and Stationary Engines

For the record, it is important to say that use of these 'large' stationary engines on
Scott Bonnar machines occurred not just in war-time, but between and after the wars!
It is true, though, that the Army SB engines were extremely large.

However, Scott Bonnar historian Grant Simpson has written that the 24" Queen City
Petrol Mower, using a Ronaldson Tippet Type 'N', was introduced in 1933, and it was being
used quite late in the post-war era:-

My research indicates that Scott Bonnar, from the late 1920s, were always looking for suitable petrol
engines. My current view is that Scott Bonnar favoured 'Australian Made' and this may explain why
they used stationary engines in peace time, had to use them in war time, and ventured into designing and
manufacturing their own engines for some models in latter years.

The rest is history.
