PART THREE - ANALYSIS

I don�t think anyone knows more about this wonderful, beastly machine. The SLSA say the photo
dates from about 1930. However, given that it has an identical Douglas twin as that appeared
on the 1925 Scott Bonnar Douglas, it is possible that it dates from that period, a few years
earlier than the approximate date and, in fact, pre-dates The SB Queen City Douglas.

My best guess is that it was a prototype for the development of Scott Bonnar�s first �true�
lawnmower, the Queen City. Authoritative member Sir Chook has commented to me that he thought
early Scott Bonnars had clear resemblances to Shanks� lawnmowers. I think this is clear proof
of that � a sort of missing link � a golf link, perhaps grin

Given that Scott Bonnar�s first lawnmowers were converted machines, it seems quite logical
that this machine formed part of the evolution that resulted in their first company designs �
the Queen City and Standards of the 1920s. I therefore date this machine to 1925, but before
the Douglas engine appeared on the Queen City chassis. The SLSA dating, I believe, is incorrect.

Alternatively, if the SLSA dating is correct (about 1930), this machine could reflect a time when the
Company was considering (again) the production of their first petrol-powered lawnmowers. Who knows?

CONCLUSION
I am confident in saying that this machine � a Shanks�s roller mower gang unit coupled to
a twin cylinder Douglas engine � could never have made it to production. It would have been
way-too-expensive. At a time when Atco � the top-selling petrol mower of the 1920s - was
proving the concept of the �lightweight� lawnmower with their cut-size-scalable Standards,
this intriguing machine seemed � obsolete. I guess Scott Bonnar saw that too!

The rest is history.
