Yes, there was - is. I have never been able to get my hands on a clean one. Somewhere, I have a copy of a copy of a copy of a copy. Will try to find it. With the exception of a few additional parts, the parts numbering scheme was similar to the stock numbers with a -970 or -971 on the end.
Why do you ask? I have 2 CR's in various stages of completion. You got some CR parts for sale? Definitely interested.
Best Regards,
Keith
