I have one of these ultra-rare (in UK anyway) rear mechs, almost brand new and never been used. Here's a photo of one on the Disreali Gears site.

(The cage is fully swung back of course, in use it hangs down from the grey pivot with Sun Tour written on it)

It's meant to bolt on to a braze-on fitting on the right hand chainstay, very similar to the bracket for the Cyclo P-2 on my Moulton Speedsix. I'd like to fit the S-1 to the Speedsix but I have no idea what the braze-on should look like and although I have the technology to either make a new bracket, or to modify the P-2 bracket I don't where to start.

Has anyone heard of this oddity or could point me in the right direction of a drawing or photo of the darned bracket please?
