Tradition 2???
I've never heard of a Kirby Tradition 2. Was that an Australia-only model? Here in the States, the Tradition followed the Classic III and was in turn succeeded by the Heritage 1HD. The next models in the sequence were the Heritage II, Heritage II Legend and Legend II. Could what you have be a G6 that has been paired up with some older Heritage II tools? There's no reason those tools wouldn't work, as long as you have a G-series hose. The Heritage II hose would not be compatible with any G-series vacuum cleaner.
