Hello Charles, It has been a while, and I don’t know if your questions have been answered, but if not, we would need to know if the rear cylinder is “phase 1”, as fitted to my 1948 K1, of which I have, frustratingly, some experience. This is the type which has the handbrake cable in-line with the cylinder and the so-called bisector component. Neil Jackson.
