They did say in the Tasmanian Apple Museum that they had had theirs for many decades. Theirs took about 10 apples on separate prongs, swift turn of a huge handle, and out sprang the sliced apples. They laid the rings (quick chop down one side) onto the surface of their woodburner, and we had dried roasted apple rings to chew in minutes. Irresistable, so I bought two of their single prong ones.
I'm sorry, Tomatoada, the Telegraph reference doesn't work for me at the moment. If you look at the Lakeland one and find something slightly longer, that would be more like the one I have.
