Lyndall Brakes | bottom right of web site page 24.
there older catalog did not show the rotors now they do..
I took it if the catalog from the Lyndall site was the 2013 release it would be just that. It isn't ! After three different downloads from different pages I found the revision you have, But the file name is the same : rev 9..... They need to clean up their files a bit.............
Thanks
