Hi all,
Your Rover Scott Bonnar was probably manufactured in the early to mid 1982 era at the Thebarton Factory. The engine was built on the 4th of November 1981 and as such would've been fitted to a newly made chassis around 5 to 6 months after that build date. A Scott Bonnar chassis can not be dated precisely as they never had a numbering system that incorporated any dates within it, thus only the Briggs equipped mowers if original can be approximately dated. The other mowers only us more experienced Bonnar nuts can approximate their period.
One thing that's different about yours is that it has a "Rudolf Red Nose" knob instead of a black unit fitted to the primary clutch lever, just wondering if this has been changed by a previous tenant.
I notice that your machine has the sticker that has only a serial number on it. This was used prior to the new green Rover Scott Bonnar Aluminum silver and green ID tag that was the next step in the evolution of the model 45.
Cheers,
BB
PS. It's a good boy and not a bad boy.
