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.
