Mike, I don't know the status of the Class 24 (1971-8 Eldo) manual. You could find out from the new Director of Technical Services, Bill Anderson (see the January Self-Starter). I expect it would be closely coordinated with the Class 25 manual to prevent wasteful duplication of effort on things like tables of options. I believe Mr. Anderson has an article coming up in the March 2008 Self-Starter which may contain a progress report.
EAM, I think we have enough help from 1975-6 owners for the time being. Thanks for asking, though. It's the 1972-4 car owners whose editing and/or writing contributions are particularly needed at this point. We could probably benefit from the thoughts of another 1971 owner as well. No Eldos or Sevilles in this manual.
