Looked into this some years ago, Steve (Simmonds) had t yet sorted his out but said he would send me a prototype to check and feedback. Nothing arrived, I chased at regular intervals for 2 years and then gave up. A friend visited to buy one of his sewing machines and he said he was just about to post out.... nothing came though.
Them Steve launched his removable wheel and mighty impressive it was however it was for earlier cars with the horn on the stalk, I phoned Steve and spoke with him and he said the central horn push was a big issue and that he was working on a type for later cars and that’s the last I heard of it.
So in conclusion it seems early type (horn on stalk) is/was available and later types (horn in centre of steering wheel) may be available now. Only way to know for sure is ring Steve.
Cain at Wolf Performance also had a solution but again there were a few horn push issues he was ironing out.
