The Sunbeam Lawnkeeper was essentially a Victa Corvette under another name.
Victa just redeployed this rather generic sounding name for their lowest price point mowers.
A bit like Mitsubishi using the Mirage nameplate for their latest 3 cylinder economy car even though it is a different type of car to their late 1990s Lancer based 4 cylinder hatchback of the same name.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
