There you go Ian...kill two birds with one stone....Supa swift and Vulcan/Big Bob. Hopefully this might answer some questions. Id say Supa swift used the Vulcan name on some of its mowers as it was already an iconic australian brand..seemingly too the big bobs relability as the ad states? What do you think......Supaswift made this? Seems highly likely.

"SupaSwift" is a truly Australian iconic brand having been established as a producer of lawn mowers by Vulcan in the Melbourne suburb of Reservoir in the 1950s. SupaSwift�s Big Bob was originally designed using parts from the company�s hot water service unit. The design has stood the test of time and the Big Bob hasn�t changed much over the years.During the 1960s, SupaSwift mowers became very popular with lawn mowing contractors because they were perfect for Australian conditions and reliable. They were also originally designed with rear handles that folded up, the catcher was then hooked onto the top of the handle to save space when transporting on trailers.It was because of this reputation that concreting company Fowler Rex bought the business from Vulcan.In the 1970s the business continued to grow and many homes had SupaSwift mowers. It was also a boom time for concreting in Australia and Fowler Rex decided they needed to focus on their core business, concreting, and sold SupaSwift to King�s Parking.Eddie Phillips ran SupaSwift for King�s Parking for many years and enjoyed it so much that in the late 70s he bought SupaSwift and made it his own. In 1983, Allpower made Eddie an offer he couldn�t refuse and became the owners of SupaSwift and the rest as they say is history.Today, SupaSwift is still highly regarded as a mower of choice for both commercial and domestic users and with the back up, service and support the product has from the Allpower Service Experience Dealer Network, is it any wonder this great Aussie brand is the success it is today.
