I know a bit about the SB 320s and their foreign origin.
I do not recognise a 320 'Nimrod'. I recognise a 329 'Demon', 'Nomad' and 'Multicut'.
Are you sure you mean 'Nimrod', and not 'Nomad'? I certainly am not ruling out the name - but I do not feel it was part of the company's Model 320 line-up.
Nimrod is correct, model 320 number 12363. I have a 320 Demon and the deck colour with the orange Briggs is common to both. If I get it I will post pics.
Hello Tom Tom That is the information I needed! Many thanks.
This mower was a New Zealand Morrison design that did sell here as a Scott Bonnar Model 320.
Much of the explanation for this must reside with NZ's Challenge Corporation, who owned both AUS Scott Bonnar and NZ Morrison at the time [mid-'70s to 1980].
This machine was sold in AUS branded as a Hunter and as a Nimrod.
My best guess is that this was a stencil rather than a store brand. I do not believe it was a factory catalogue model.
