Nigel, at the risk of badgering you to death(!), I’ve just come across a couple of copies of “Southern Way”, secondhand, which feature the C2/C2X classes, at a saving over new. Just in case it would be of interest, heres a link to one of them. The second part is in vol.10, also available from the same seller.

All the best.
