G'day
wce, Gizmo, Mowerfreak and all
This is such a complex topic and I have attempted to piece
together some understanding in recent years.
Many thanks to
wce for saving this one.
Yes, the first model Sunbeam rear-discharge lawnmower.
Has the KAV74 2 stroke. spec number 6613 ( specification ? ) serial 8705. Can a manufacture date be determined from these numbers?
I regret the answer is NO.
No Kirby production records appear to have survived.
I am compelled to say something here:-I do not feel the Sunbeam story has been told and I do not confess
to understand all but the basics...
Sunbeam made its name here in the wool industry - hair clippers that
made sheep look aggressively heavy metal.
But post WWII, Sunbeam AUS - Through Sunbeam USA designs - made a massive
contribution to domestic appliances - hair/beard clippers (for humans) fry pans, and etc.
Just like in the USA, Sunbeam became an electric
appliance maker.
Remember the Sunbeam 'Vertical Grill'?
Out of this came the
Sunbeam electric lawnmowers of the 1960 and beyond.
These were made here, and Sunbeam AUS saw the opportunity.
The first Sunbeam petrol mowers were the
Fastcuts.Heard of them ...? I am still to write about them. These were a ridiculous
USA design - with off-set wheels - but with an AUS single one-point
height adjuster. Who did this? No one knows. ..
A USA pressed steel base - with off-set wheels - but with a complex
single-point height lever. I have suspicions...
Then came the Sunbeam 'blue' rear-discharge lawnmowers of the
late 1960s. Thee are the contentious ones, and I have asserted that
Victa designed these, but with USA Sunbeam touches - like a bar blade!
When Sunbeam acquired Victa in 1970 the cat was out of the bag.
We see the same chassis, but with Victa engine and that beautiful orange/brown scheme.
Sorry for long rant.
