Hi Jack, Thanks for that I was way off with the Swiftsure thought.
Yes Eaton have a lot of transmission systems and I think it was discussed on ODK before that Eaton had the patent for the Spring Starter.
I have been looking at an idea that Vulcan did have a role in building the Supa-Swift utility in the 1960 s ( first model big bob) all speculation no proof but I was looking at Vulcan Electrics in Burwood Victoria as a possibility.
