Hi Jack,
Thanks for your time & short article.
It does have "Made at the Subiaco address" & together with the dated engine it must be an early 1970's machine. The rear drum is a one piece unit. Yes, very strange that it has a 17 on the plate when it's a 20 inch - maybe a 'friday' job in the factory???
The beauty about this machine is that all cad plated parts are still like new - no rust. and also that the cylinder has never had a sharpen - engine runs like a dream too.
Again - thanks.
Peter.
