Hello vcomm, HT6 and Joe
Well this is a new twist.
I have to agree with Joe & HT6: the engine must be a re-power.
What I can't answer is whether this machine is a product of a Rover-Masport
deal; or an arrangement between Scott Bonnar and Morrison made prior to the
1980 takeover of SB by Rover, and also before the 1986 takeover of Morrison
by Masport.
My best guess is that this is a Morrison-Scott Bonnar made in the late 1970s.
At his time Scott Bonnar were selling Morrisons as Model 690 Scott Bonnars.
I do not believe vcomm's machine was sold here - Scott Bonnar had a full line-up
of rotaries - the 420, 520 and 720 machines. The 320s were utility mowers here.
Soooo - I think this machine was part of a reciprocal deal, whereby these mowers
were sold in the NZ market and branded as Scott Bonnars. This machine must have
been privately imported.
All very interesting.
