Hi Alex, I have just spoken to a chap today from Rover Australia, and he confirms that the Victa Imperial was manufactured in New Zealand by Morrison Mowers, imported into Australia by Masport for Rover-Scott Bonnar and badged as a 690 Series Scott Bonnar....Please see the pics below; Hoping this might be of interest to you.
