Here's an example of the Australian Centurion brand. As you'll see: same logos, clearly from the same sources as WSI, even a repeated model name, Turbo, but a very different bike. While the US Turbo was top of the line, from 1983-94 only, this is a late 80s bike and more high-to-middle of the pack, more like a LeMans RS: Champion #2, Suntour Ole group, etc. Biopace chainrings but that has to be a sub at some point. I have seen other 'Turbo' model bikes from Oz but recall them being more like an Ironman...maybe there were different levels of it.
