I was referring to the 70s and I read about Rover being considered a step above Victa in the 1990s sometime, not the heady days of the 70s when Victas weren't offered in steel frames and were well made mowers as well.
I am focusing on the alternatives to the dominant Victa brand at the time. Scott Bonnar, while best known for their reel mowers, they made some mean rotaries as well, including their very well built high arch domestic range. Rovers with the blue chassis and chrome wheels were top notch quality wise as well.
I only ever first heard of SupaSwift in the 1990s thanks to television advertising giving me brand awareness.
I am amazed how fast back they went and how prominent they were way back when.
