For sure, finding accurate information on the Supa-Swift brand history isn't at all easy. It's not made easier by the brand name having changed hands quite a few times over the years, either.
Despite Allpower's claims, I doubt that Vulcan was the original owner of the brand; probably just one of the succession of owner companies. They did own it in the late 1970's, going by ads for 'Vulcan Supa Swift' mowers that appeared then, but by the mid 1980's it had passed on to Jetfast Industries in Sydney [founded as Bragg Industries], later Jetfast Supa-Swift P/L. Supa Swift also distributed Greenfield ride-ons for a time [1970's on], co-branded with their name.
Allpower Industries has a bit of interesting history too. As their website says, it was founded in 1977 as Ariens Echo Australia, but there's more to the story. The founders were a group of former managers of Mobilco Limited, the previous importer of those brands among others, and also a manufacturer of farm equipment. Mobilco had been closed down after an 'asset stripper' got control of its parent company, Pizzey Limited, in 1976. The youngest of the ex-Mobilco crew, Keith Billing, ended up as sole owner of Allpower, and sold out to a 'private investor syndicate' in 2007.
Reference - industry mag article CyberJack is on the money about Allpower ceasing manufacture, but this seems to be a recent occurrence. Allpower's CEO from 2011-14 lists 'outsourced manufacturing to China' as one of his achievements in that role...
