Not pciking on you, but the post above is not much use without the part number off the non tornado plug. They also did one for the steel base.
There was an older alloy base slighly different to the one in question, the model before if you like and they may have also done one for it as well.
Ive got a mulch plug here for a steel base, but its dark out and im in my PJS.
Cheers.
