Yep, Dennis, your spot on, I have worked from this system chart as well, and the only bit i'm waiting on from Claude is the No 66 that screws onto the Extender Q. i have all the others, as i use some with the CA35 and wide T-mount for the 5D
Your right, why they have so many bits is beyond me too, it gets very confusing.
Thanks for the trouble you went to to check it out, maybe when the other bit arrives all will be well.
