Hi again
Ian,And thanks for posting that information as it proves my point...
All 17" and 20" Model 45's post 1978 were twin rail machines.
It is
fact that the Scott Bonnar Thebarton manufacturing plant in Sth Australia closed its doors for the last time in 1983.
The manufacturing operation was then transferred to the Rover Mowers Australia factory in Brisbane. They continued to make the 17" and the 20" machines in the same colour hammertone scheme and pentagon decals.
I am not exactly sure of the date the name changed to Rover-Scott Bonnar, but it was in the early 80's and as your brochure shows definitely by 1984.
The Rover-Scott Bonnar address in your brochure shows Beverley, this was the authorised SB dealers address, not a manufacturing plant.
You'll also notice that the machine featured in your brochure is a 20" machine not a 17"..... as evidenced by the 6 segments in the cylinder reel (the 17" has 5) and the length of the cutter clutch engine shaft.
You will also notice in the last pic of the rear of the machine, that an ID anodised plate stating Rover-Scott Bonnar, usually found on the rear rail adjacent to the clutch-fork is missing, indicating that this may have been a transitional machine.
All good stuff!
